Determine the age of the dog on teeth or by external signs is necessary for animals that do not have documents. The least error is given by the method of determining the age of the dog in the teeth. The dog grows quickly especially in the first year of life. Therefore puppies consider the regularity of growth and change of teeth, and in adults it is important to erase teeth. It is worth noting that the criteria below are suitable for healthy dogs that eat well and are kept in good conditions. Incorrect contents or diseases disrupt or slow the growth of teeth.
How to calculate the age of a dog to a year?
Puppies are born toothless. The first milk teeth are usually cut for 20-25 days. First, the upper and then the lower incisors and fangs appear. In a month the puppy already has all the front uterine teeth.
In puppies a little older, we pay attention to trefoils on the milk teeth. On the hooks of the lower jaw, they disappear in 2.5 months, on the middle teeth of the lower jaw, the trefoils disappear in 3-3.5 months, on the edges - at 4 months. These terms may deviate slightly - it all depends on the mother's nutrition and the characteristics of the puppy itself. Perhaps the discrepancy in one litter in 7-14 days.
In 4-5 month old pups there is an almost simultaneous change of the dairy cutters of both jaws. In turn - hooks, medium, edge. Usually within a month the change of teeth ends.
Fangs erupt in 5-6 months, first on the upper jaw under the dairy, and after 10 days on the bottom in front of the dairy. This is an interesting time, because For a while, dairy and persistent fangs can be observed simultaneously.
About 10 months a good strong dog does not have a single milk tooth. By 12 months, a normal healthy dog has all permanent teeth. They are not at all worn out, white, shiny, fresh.
In large dogs, the change and appearance of all permanent teeth occurs earlier than in small dogs. Ears and diseases can stop the growth of teeth.
In many ways, teeth determine the age of a puppy dog. It is generally believed that with the appearance of all permanent teeth, the puppy passes into adolescence.
From now on, in order to answer the question of how to determine the age of a dog, it is worthwhile to carefully look at the erasure of trefoils on the incisors and pay attention to how much fangs have stood out.
How to calculate the age of an adult dog?
To understand how to determine the age of the dog in the teeth, it is worth knowing that the teeth of the dog begin to wear off for about 18 months.
- in 2 years the hooks of the lower jaw are erased, and middle teeth begin to wear off;
- in 2.5 years, the middle incisors are erased, the teeth lose some of their luster, dim;
- in 3 years, the deletion of the hooks of the upper jaw begins. At 3.5 years, the tubercles on the upper hooks are erased;
- in 4 years, the tubercles begin to erode on the upper incisors. The erasure lasts six months;
- in 4,5-5 years begins the erasure of the margins of the lower jaw;
- at the age of 5 the fangs become blunted;
- at the age of 6 the upper incisors are erased and become concave. Fangs noticeably blunted, often covered with dental calculus at the base. Teeth acquire a yellowish hue;
- at the age of 7, a concave, so-called back-oval shape, accepts lower hooks;
- in 8-9 years on the lower middle incisors the back-oval form is manifested;
- in 9-10 years the same happens with the hooks of the upper jaw;
- in 10-12 years, the teeth of the dog begin to stagger, often take the wrong position, which affects the bite. Some dogs start to fall out of their teeth. This pattern is difficult to track, often it all depends on the characteristics of the dog.
The above indices can be more or less deflected due to an incorrect bite of the dog. Also, the erasure of teeth affects the wearing of hard objects in the teeth and the habit of gnawing stones or an enclosure. Feeding with solid food helps to quickly erase teeth, while mushy food spares the teeth, but does not give proper training and teeth weaken.
