Hi everyone! here I am again with another question. My friend has one of the pups my Kaluha had in in December and she just called me very worried because she says the pup isn't eating and seems sad. She also says he has one of his testicles really hard and the other is normal. Has this ever happened to anyone else's pups? He is currently 7 months old. She will be taking him to the vet in the morning, but would like to know if there's anything she can do for him now. Any and all help would be greatly appreciated!!
