I have a ten week old female. Last week she was favouring her front leg so I took her to the vet for x rays... Turned out to be a "muscle injury" from playing too much. She was on anti inflammatory drugs for a week and seemed fine. Last night she was super lazy and favour her hind legs. She can stand and she can walk but it's more of wobbling walk. She sits a lot and doesn't yelp when I touch her. Am I just being completely paranoid? I can't keep going to the vet every week they will think I'm nuts! Suggestions???
