Nowadays, keeping pets is very popular around the world, especially dogs. However, many netizens have reported that the dogs they bought home are sick and infected with infectious diseases, etc., and they have not taken care of them poorly. So be sure to understand what you need to pay attention to before buying a dog to take home.

1. Look at the coat color. Healthy puppies generally have clean coats, smooth and straight hair, shiny and tight back hair, and smooth and elastic skin.

2. Look at the nose. A healthy puppy's nose is moist and smooth, and feels cold to the touch. If the nose is very dry and there is purulent secretion around it, or the nasal mucosa is congested and ulcerated, it means that the puppy is sick.

3. Look at the tail. A healthy puppy's tail swings freely and is usually pointed upward.

4. Check the body temperature. The normal body temperature of a healthy puppy is between 38.5 degrees Celsius and 39 degrees Celsius.

5. Look at the anus. A healthy puppy has a clean anus and anal glands that are not red or swollen. If the puppy's anus is very dirty, it means the puppy has diarrhea.

It is recommended that parents who love pets should take their newly purchased pet to the designated unit of the Municipal Animal Husbandry and Veterinary Bureau to receive some vaccinations in a timely manner. Young pets should not be bathed frequently and should not be fed too much.
