First, after the teeth of the puppies grow together, there are 28 in total. After replacing them with permanent teeth, there are 42 in total after becoming an adult dog.
Due to the nature of the food fed and the feeding method, the degree of wear of the dog's teeth will vary, so for adult dogs, there will be certain errors in judging age. So here we will only talk about the methods of judging the age of puppies. After all, I know how old the puppy is, and the owner keeps raising it, so naturally I know how long the dog has lived.
About 20 days, the dog's teeth begin to grow. At
4-6 weeks, the incisors of the breast are in a uniform length.
After nearly 2 months, all the breast teeth were long, white, thin and pointed.
2-April, replace the first breast incisors
5-6, replace the second and third breast incisors and breast canine teeth. After 8 months, all of them will be replaced with permanent teeth.
When I was 1 year old, my teeth were long and white, and there were sharp protrusions on my incisors.
Knowing this, you can almost determine the age of the puppy. Full-month dogs have full-month feeding methods, and three-month-old feeding methods are different, so it is still necessary to know the age of the puppies, and this also involves the issue of getting vaccinated.
