i could sure use some advice. ben our 3 year old male came up lame today, while chasing our goat. he has hd, in the same side, but appears to be the knee or ankle that is being favored. being a holiday weekend, i've only been able to talk to our vet via the phone. how can i tide him over comfortably until tues? the vet gave me small dog advice, i need big dog advice from a pro, thanks rob
