When do dogs change teeth? When do puppies change teeth: age of small and large breeds
The order of changing teeth in a puppy
The very first teeth in puppies appear at the age of eleven to fourteen days. These are fangs, behind which incisors and premolars erupt in an even row. By one month, each baby already has twenty eight excellent teeth, fourteen in each jaw.
At the age of three months, the gradual replacement of baby teeth begins. The duration of the shift can vary from two and a half to six months, until the last premolar grows. In small puppies, the change of teeth may take up to the age of eight or nine months, dogs large breeds Already at six months they show off a snow-white grin.
- First of all, the puppy's incisors fall out, the owner does not even notice this, since small puppies very often simply swallow their milk teeth. The roots of the incisors dissolve and serve as building material for permanent teeth.
- A little later, the primary premolars become loose and fall out. Simultaneously with them begins fast growth molars and premolar 1, the absence of which is a disqualifying defect in most breeds.
- The last ones to fall out are often the fangs.
After changing teeth, the dog should have forty two teeth. Twenty of them are located in the upper jaw, twenty-two - in the lower jaw. An adult animal must have:
- 12 incisors;
- All 4 fangs;
- Exactly 16 premolars;
- And 10 molars.
If it is not possible to find out what the approximate age of the puppy is, then you can determine it by its teeth.
- Yes, y one month old puppy All milk teeth are present, they are small, sharp, and arranged in a row.
- A two-month-old puppy has more widely spaced front incisors, as the jaw is growing rapidly at this time.
- At three months, the incisors already look very low, some of them are lost. Four month old baby already has two to four new incisors.
- At six months the puppy already has full row permanent incisors, first premolars present, primary canines may be absent, displaced by growing permanent ones.
- A six-month-old large breed dog has everything permanent teeth.
Teeth can take up to a year to grow, and this is due to difficulty in the eruption of individual teeth. The owner can feel the emerging tooth under the skin of the gum, which cannot break through. In this case, a small resection of the gum is usually done and the tooth comes out.
How to care for your puppy's teeth
Small puppies are constantly gnawing on something, but the teeth of babies aged three, four or more months are especially itchy. At this time it is useful for them to give large raw beef bones, various rubber balls And . It's okay if blood appears on these items, it's common symptom that another tooth has fallen out.
Very often a young dog's teeth grow in two rows. It is better not to wait until the permanent tooth displaces the milk tooth, as the delay can cause dentition problems. In the best way get rid of baby tooth is its loosening. The tooth is loosened for a few minutes a day, after which it falls out painlessly and unnoticed during play.
Temporary baby teeth do not require special care, but permanent teeth need to be periodically brushed with non-foaming toothpaste. This will relieve the dog from the accumulation of plaque and the formation of tartar, and unpleasant odor from the mouth. As a preventive measure, you can give a carrot or an apple to chew on. Bones should not be given after a shift, as they wear down the teeth.

Puppies are born without any teeth. In the first month they feed exclusively on their mother's milk. From the first to the second month of life, babies already grow a set of temporary teeth, which are called dairy. There are 32 of them in total - 16 molars, 12 incisors, and 4 canines. When all the temporary teeth have appeared, the puppies begin to new process– dairy ones begin to change to permanent ones. As a rule, this occurs from the third month of the pet’s life. In puppies, the change of teeth is almost the same for any breed (it may only differ slightly in timing).
The process of changing teeth in puppies
Tooth loss occurs gradually during the first year of the animal's life. The first to fall out are the deciduous incisors and hooks. By the end of the fifth month, the edges and middle incisors are replaced. Milk fangs fall out by six months. They are much longer than all teeth, located between the molars and incisors. The most resistant molars, they are the last to fall out, one by one, and finish changing by seven months.
Milk teeth are small, they either fall out or the puppies swallow them. As soon as a temporary tooth falls out, a permanent one appears in this hole; it grows very quickly. Teeth grow along the canals from which baby teeth fell out. Therefore, if a temporary tooth does not fall out, then it is better to remove it so that the permanent one does not grow in in the wrong place. It is important that the animal develops the correct bite.
Teeth change faster.
By the end of the tenth month, the pet should have no milk teeth. When he turns one year old, healthy puppy will have all snow-white sharp teeth.
U adult dog 42 teeth, of which 20 are on top and 22 on bottom.
Among small or 
up to eight kilograms is a common predisposition to problems when changing teeth.
To save healthy teeth the puppy's food should contain required amount mineral elements and calcium. Diseases in your pet can delay the loss and growth of new teeth. When a puppy's teeth begin to change, he chews a lot on everything indiscriminately - he needs to be given bones or cartilage for this. During this period, there may be indigestion and even a rise in temperature. If you have problems during a shift, you should consult a doctor, especially if the owner plans to take part in exhibitions or competitions with his pet. After all healthy teeth emphasize the thoroughbred nature of the dog and are the key to its longevity.
If a puppy grows up at home, at a certain point we begin to observe how, without apparent reason His mood begins to change. Sadness, fatigue, and favorite games - these symptoms are typical for the period of change of baby teeth in puppies.
How to help a puppy with changing teeth?
Bad feeling This is due to the fact that the baby teeth have not yet fallen out and the permanent teeth have not yet grown in. Due to inflammatory process in the gum area, it is difficult for the puppy to eat. We are required to help the baby survive this period, creating maximum comfort for him. Many novice dog breeders are interested in what can be given to a puppy when changing teeth to alleviate his suffering. Since teeth fall out with difficulty, your pet needs to strain his jaws to get rid of them. It will be relevant to add such delicacies to your food as beef bones and stringy meat. If we leave the puppy alone with his problem, he may develop two rows of teeth, which will make the situation even worse. Sometimes only a doctor can help a dog.
The order of changing teeth in puppies
There is a certain schedule according to which a puppy develops certain teeth. The appearance of baby teeth is typical for one month old baby or when he is only 20 days old. The exception is the baby, whose milk teeth erupt at 45 days.
Nature designed the puppy to have 14 baby teeth in each jaw and to be able to use canines, incisors and molars. The canines appear first, followed by the incisors and only then the molars. If the schedule is disrupted or an abnormal bite occurs, the puppy must be taken to the veterinarian.
The replacement of milk teeth with permanent ones is typical for dogs at four months of age, with the exception of small breeds, in which this period occurs at six months of age. 
The whole process takes about two months and eventually 42 new teeth grow, large quantity which is located on the lower jaw (22 teeth). The process of tooth replacement begins with the appearance of the incisors, followed by the eruption of molars and premolars. Fangs complete this difficult period life of a puppy. When we observe the presence of all permanent teeth on the puppy’s jaws, the milk ones, as a rule, are no longer there. But this happens only in the absence of pathology, the causes of which are numerous. The health of your pet’s teeth depends not only on inheritance, but also on our attention. Periodic examination of a puppy by a doctor is a good preventive measure for diseases in adulthood.
Hello friends! I decided to write several articles about teeth in animals, cats and dogs, the first topic of the series will be about the change of teeth in dogs. I will also show you photographs from personal practice, where you will see how teeth change, how many there are in puppyhood and how many there are in an adult dog.
I'll start with the photographs, here you see normally developed teeth in a 1.5 month old puppy (a cross between a shepherd and a Rottweiler). 
Milk teeth are small and sharp, there are gaps between the teeth, which will increase as the jaw grows, this is how it should be.
This is a spaniel puppy, he is about 4 months old, please note upper incisors, they have already changed (marked with a red arrow), the fangs are still milky. 
And on this are the teeth of a young diver, our old friend Vakhtang, he appeared in several videos and other articles. These are already permanent teeth, but their growth is not yet complete. 
Here you can see two fangs (where the red arrow is), one is milky, and next to it the permanent one has already erupted. This phenomenon often occurs and the tooth can be easily removed by yourself with a slight movement, see in the first photo how I did it.
But if the fang does not wobble and is held firmly, then it is better to consult a doctor to have it removed by a professional. But we will talk about dental diseases in other publications; now we are considering the norm.
A little anatomy
In this photo you see the skull of a dog with well-preserved teeth, let's draw an imaginary line in the middle. 
In anatomy, this plane is called sagittal, which divides the object lengthwise into two symmetrical parts, in our case it is the head.
After separation, we will get something like this:
Let me clarify that here you see a full set of teeth of an adult, healthy dog, but this is ideal; in practice, the complete set is not always present.
Letter A I marked the upper jaw with a small letter V bottom. There are 10 teeth on the upper jaw, and 11 on the lower jaw, do not forget that this is only half, on the other side the same number. In total, an adult dog has 42 permanent teeth.
Note, blue The incisors are marked, the canines are green, the premolars (or false molars) are red, and the molars (true molars) are yellow.
Dental formula
The designations used in veterinary dentistry are as I have depicted below. Here we see the total number of teeth: 
In the form of a fraction, note which teeth the dog has on the top and on the lower jaws On the one side. Capital letters taken from Latin name corresponding type of teeth - incisors ( I ncisives), fangs ( C anines), premolars ( P raemolares) and molars ( M olares).
An adult dog's dental formula will be as follows:
As I showed in the picture above, a dog has 3 incisors, 1 canine, 4 premolars and 2 molars on the upper jaw, and on the lower jaw there are also 3 incisors, 1 canine, 4 premolars, but there are 1 more molars, that is, 3.
And this is the formula for a puppy, you see that the same set of teeth as adult, but there are no molars, which is indicated by the number – 0.
Puppy's teeth
The puppy is born without teeth; they appear around the 30th day. First, the canines erupt (at 3-4 weeks), then the incisors (at 4-5 weeks), and along with them the premolars, but puppies do not have molars. In small breeds, the onset of tooth appearance is delayed and extended over time.
If we take, for example, a Yorkie or a Chihuahua, their first teeth appear at 45 days.
In total, the puppy has a full set of 32 baby teeth, all the same as you saw in the diagram above, only without the molars (marked in yellow).
At about 3.5-4 months, you may notice that your puppy’s teeth have fallen out and new, larger ones are appearing in their place. Don’t be alarmed, changing teeth in a dog is not as painful as in children.
Yes, appetite may worsen due to painful sensations, an unpleasant odor from the mouth, diarrhea and other symptoms may appear. But in most cases you won't even notice this process.
The incisors are usually the first to change, then the premolars and molars appear in parallel, and the permanent canines grow last. Normally, a dog’s teeth change is completed at 6-7 months.
Conclusion
Friends, in this article I have given general information about the change of teeth in dogs and about animal teeth in general, let me remind you that this is one publication in a series, there will be a continuation later.
Also keep in mind that correct shift teeth largely depends on proper nutrition and dog care. If the body does not receive necessary substances, then, accordingly, the teeth may erupt later, or they will not be strong.
During the period of teeth change, a dog needs to chew a lot, for this they use special good quality treats, not like those we talked about in, and they also need toys.
Moderate load on the jaws improves metabolic processes in tissues, then teeth form and erupt on time and correctly.
A few more words about playing with a puppy, I often noticed that many play with rags and ropes, trying to take a toy from the dog - who will pull who? Yes, I agree, such games are fun, but you can damage your breasts or your permanent ones, so it’s better to avoid such competitions.
That's it, I'll wrap it up, we'll soon talk about teeth changing disorders and their diseases, but for now you can watch the video. Also, if you liked the article and want to help develop the project, share it on in social networks, I will be pleased.
Such a toothy one!
If you don't know how and when dogs change teeth, be sure to read this article, which contains all the basic information regarding this topic.
So, first of all, we note that the change of baby teeth in dogs, regardless of the breed, takes place in almost the same way (with only minor differences in timing). There's only one general feature: large breeds go through this stage somewhat faster than representatives miniature breeds(read how this happens in Yorkies).
All puppies do not have a single tooth at birth. Like newborn children, they consume only liquid food - mother's milk.
- When 20 to 25 days have passed since birth, the dog becomes the proud owner of its first milk canines.
- After about another 10 days, that is, on the 30th – 35th day, the incisors erupt.
- The last baby teeth appear between the 30th and 60th days of a puppy's life.
Some time after all the temporary teeth have taken their rightful places, a new process begins. So we come to the answer to the question: in how many months or when do milk teeth change in dogs? The change is carried out gradually, not in a month or two, but throughout the entire first year of life:
- The first primary incisors, the hooks, fall out quite early, even before the age of four months.
- By the end of the fifth month, the replacement of the middle incisors and edges begins.
- By six months the fangs change.
- The most persistent false-rooted teeth do not give up their position until their owner is ten months old. Nevertheless, slowly, one after another, they fall out.
Thus, if your dog is completely healthy and develops in accordance with all norms, by the end of the tenth month of life he should not have a single baby tooth left. When he turns one year old, his " Hollywood smile“should demonstrate snow-white, strong and sharp teeth.

Further, with age, the crowns begin to wear down a little. Sometimes they are erased almost to the ground. Most often this happens to old dogs who, in their youth, liked to chew on something very hard, say, metal mesh when kept in enclosure conditions, or something similar.
By the way, the degree of wear on the crowns is easily determined.
How to help your pet?
How does a dog feel when its teeth change? In most cases, the loss of old teeth and the eruption of new teeth is almost painless. The only discomfort can come from an itchy feeling in the gums. At the same time, the puppy strives to scratch them in the only ways available to her:
- chew wooden furniture,
- chew the owner's shoes,
- tinker with the binding of the book...
If you value your belongings and furnishings, make sure in advance that your puppy has several devices designed specifically for chewing. It can be:
- rubber bones,
- teething toys,
- delicacies in the form of pig ears, cartilage and the like.
Now available in pet stores a wide range of all sorts of inexpensive things designed to protect your things from damage.
Also, sometimes the dog’s temperature rises, but not much, by 0.1-0.3 degrees. Such an increase in temperature should not cause panic, since such a reaction of the body to the changes occurring to it is within normal limits. You should be wary only if the dog has become lethargic, inactive, and has lost its appetite.
If your pet has any of the above symptoms, it would be a good idea to contact your veterinarian. In addition, a visit to the clinic is necessary if a molar begins to grow next to a baby tooth that did not fall out in the prescribed time frame, resulting in the formation of a second row of teeth on the same jaw. All this is fraught with the formation malocclusion, so it’s better to remove extra teeth immediately.
By the way, when choosing a puppy, be sure to pay attention to the condition of its parents’ teeth. This important rule It is better not to ignore it, since all dental problems of a dog are inherited by its offspring. Thus, you can find out in advance how much trouble this or that puppy will cause you in the future.
