Concerned.
My sister had to bring her border collie to the vet hospital today because he hasn't been himself the last day or two. They weren't sure if it was pneumonia or some sort of heart condition but we heard a little while ago that he has an enlarged heart.
He has to take medicine for awhile and have an ultrasound done. He's an older dog, almost 13 years old! I knew when I was taking care of him yesterday that he wasn't feeling well. I hope he'll be okay. My sister's had him since he was a puppy so he's like her baby.
