His bone structure looks weak what can i do to improve that some more pics hope he is a stock medium coat
Bone or muscle? You are in the middle east? India? Diets for dogs in these regions seems to be limited and I've seen some pretty horrendously unbalanced homemade diet posted here too. What are you feeding him? He's just a baby. Doesn't look more than 8 weeks to me so I'm not sure what you are expecting him to look like?
My friend has a gsd puppy too and he is also 8weeks but much better in bone density yes im from middle east right now ive started feeding him mera dog food i bought him royal canin but whenever i feed him he gets diarrhea
