Boston Terrior Sudden weakness
My Boston Terrior suddenly seems to have weakness in his legs and does the minimal amount of walking possible. This just started happening last night. When he stands his legs shake and he immediately sits down. He doesn't seem to be in any pain, he doesn't yelp when i rub his legs or pick him up. He does have an appetite, he ate all of his food this morning. He also had a bout of diahrrea for three days where it was pure liquid, but at the time we attributed that to someone giving him pumpkin pie at Thanksgiving. He has had a pinched nerve in the past, but he's never acted like this before. If anyone can give me any insight on what might be wrong, I would greatly appreciate it.
