My greyhound, Penny (see post below) just passed away. Took her to the dog park, she chased balls, and her panting afterwards got rough. I didn't understand what that meant. Vet said it was her heart. Quicker action might have saved her. So might a bit of insight/ an ability to read the signs. It's not rocket science. I feel so guilty. And miserable. And alone. @joneshowdareyou do I deserve it all?
