We picked up our 3-year-old greyhound after she was boarded for a week at the local animal hospital. When we got home we discovered that she had the rash in the photo below.
We took her back to the vet where she was boarded, and they don't know what it is. They're saying that it's bruising and did blood work. The blood work numbers look absolutely perfect for a greyhound, but they're concerned about her low white count and high platelet count, low for most dogs, but perfect for greyhounds.
The second photo is from the next day. They drew circles around the discoloration to gauge any change. The photos show that it got closer to purple in the day that passed.
I've read that rashes happen for various reasons, and the vet is calling it a bruise.
Is this something to be concerned with?
