Pup keeps hurting his front leg
my 9 month old lab pup has just started to have a re-occurring injury to his front right leg. It seems he keeps hyper-extending it outwards accidently when playing. The first time he did it he just took a couple hobble steps before laying down and was back up running within 1 min. The next time he yelped when he did it but went back to normal fairly quickly. I've been trying to play with him very gently but he just goes after whatever toy so hard he hurts himself. He just did it again and yelped for about 10 seconds and its starting to freak me out.
i called my vet but they are closed today and Ill call tomrw. I am planning on pretty much eliminating his activities for a few days to let it heal. Any other suggestions to help or how long I should restrict activities?
