Do you know what your dog’s normal body temperature should be? Do you know what body temperature counts as a fever? Are you confused when you take his lab test sheet? What if you know nothing about your dog’s health and physiological indicators? If you know, then I really want to criticize you for your incompetence as a dog owner! Let me clear your eyes. The following is a list of dog health physiological indicators. You'd better write it down:

1. About dog teeth

Puppy: Upper jaw: six incisors (the teeth between the canine teeth that cut off food in the front of the mouth), two canine teeth, and six premolars (the teeth behind the canine teeth that are used to grind food), so the total size of the upper jaw is 6+2+ 6=14 teeth, including the lower jaw, a total of 28 teeth. The teeth are replaced between 4 and 5 months, and all are replaced after 7 months.

Adult dog: Upper jaw: six incisors (the teeth between the canine teeth that cut off food in the front of the mouth), two canine teeth, eight premolars (the teeth behind the canine teeth that are used to grind food), four posterior molars (near the base of the tongue) molars); in this way, the upper jaw has a total of: 6+2+8+4=20, and the lower jaw has six back molars near the base of the tongue, so the lower jaw has 6+2+8+6=22, so the adult dog has a total of 42 teeth.

　2. About water

Dogs can lose almost all of their fat and nearly half of their protein and still survive, but they will die if they lose only 15% of their water, so it is very important to give your dog water.

3. About the dog’s skeleton

The number of bones in different types of dogs is slightly different. On average, dogs have 134 axial bones (50 spine bones, 50 hyoid bones around the skull and throat, 34 ribs and sternum), and 186 appendage bones (forelimbs). 90, hind limbs 96), and 1 male penis, a total of 321 pieces.
