Running all over like a maniac... Fell over a large rock or ran into it or something. Came up non weight bearing on back left rear leg. Still barely weight bearing. Didn't yelp or make any pain sounds upon impact. He is fully insured in case it is something ugly. Never insured a dog in my life and never had any breaks or ligament damage on any dogs in my life... but I had a FEELING that this dog might need insurance. I will try and get him into the vet Saturday. Bleh... Truly this dog is an absolute nightmare to own. I am REALLY trying but it is not easy at all. For once in his life.... He is calm, and it is for the wrong reasons. He will barely get up... And only if he HAS to. Oh and in case you are wondering why Oreo is wearing a bell... The puppy RAN OVER HIM by accident in a frenzy and scratched his face and he needs the bell while it heals.
