Sheltie puppy limps after every nap.

Oh if I still see him limp after he is fully grown then I’ll take him to one and probably not have him do sports. Bummer.

No problem doing sports unless there is a structural issue. But like people active dogs can get knocked out. Certainly do not do repetitive training until he is a year old IMO. Lots of training you can do without being repetitive.
