Hind legs collapsing
Today my 6 year old German Shepherd's hind legs collapsed from under him after I had just got back and was out in the garden playing ball with him. It is the first time it has happened and lasted roughly 2-3 mins. As he lay on the grass I massaged his hind legs and he rolled on his back and since then he has been fine! Ate his dinner and played ball. So obviously I was worried and googled it (I know I shouldn't!) and seen that it could be something like: heart failure, arthritis, nerve problems, exhaustion etc..!
I am going to go the vets tomorrow as they are shut today and see what the vet says but was wondering if anyone had any other solutions!?
