When the puppy was born, its mouth looked like that of a rabbit, and there was a crack in its upper lip. Grow up.

Puppies are born with cleft lip and palate because bitches can't keep up with nutrition during pregnancy and lack vitamins. Bitch should take some vitamins or take two tablets a day during pregnancy. Another possibility of cleft lip and palate is that the bitch was infected with the virus during pregnancy, which affected the development of the fetus.
