Puppy wont walk on his leg

my 7 month old beagle (he's huge) keeps injuring his back left leg and his front right leg. The vet seems to think its just a sprain all the time but he couldn;t be sure without an Xray. We weren't ready for the cost of an Xray so we would give him anti inflammitory and he'd be his same crazy self in a week or 2. But it keeps happening, maybe 4 times so far in total. could he have broken his leg and keep re-breaking it? how can i tell without an Xray? What are the symtom differences between a fracture and a pulled muscle?

Please help =) thanks

YOUR vet can't tell without an X-Ray!! Certainly no one here will be able to diagnose your dog's problem.

It could be a break, it could be arthritis, it could be tendon damage, it could be bone cancer. And those are just the things that come to mind - I am not a vet.

Your dog needs to see a vet and get x-rays done.

This is not the first time you have asked this question. Please see the vet for xrays. That is the only answer you will repeatedly get from the members of this site.
