Oh Mike, I'm so sorry to read about Eddie's injury! Sending lots of prayers that it's nothing more than a pulled/strained muscle. Only problem I've had with mine is Gabby injured her back jumping off the bed and would wimper and whine each time she jumped. We took her to the vet where he diagnosed a slipped disc - she had to stay at the vets on steroids for a couple days and then was allowed to come home. That's been a few years back and she's made a full recovery
I know the same will be true with Eddie. Gabby and Gage send lots of puppy hugs that he's feeling better soon!
