My dog max was badly injured by a car when he was younger.. i had to give him a pill of something to prevent arthritis on his other leg(since one had to be removed) They said it was possible that when he got older he could possibly suffer from arthritis. What do you guys think is most likely to happen? Do you think he will be ok? He kind of walks weird on his only leg in the front too. If he did get arthritis what do you think they could do for him? I've been so worried about this for years.
