She had a full tear of her ACL back the end of July and had surgery the first week of August. she was recovering great up until about 2 weeks ago. It started with her being slightly off in her gait to this week being 3 legs lame. When I went in last week to check they started me on different exercises. When i went in today, they scheduled me for an emergency surgery spot for tomorrow. The vet want sure what's going on but wants to sort it out ASAP for her.
