Max was ill, but not ill enough to be killed. It was just last sunday I was playing with him & was running around in a parkinglot with him.. Rob drove Max & I 200km (to & from) to take Max to see santa at petsmart. Max wasn't in anypain & the vet even told us that, hes just a bit weaker then usual. but how many 10 yr old dog play longer then 2 hrs? that was Max cut off time & thats when he wanted to rest. I'm sorry but 2hrs of play is good for any dog.
