Behr, my Rottie is not well, wobbly on her back end, off her food, heavy breathing & some blood in her urine, we are booked into the vet at ten past four & I hope I'm wrong but I don't think she'll be coming home with us, she is ten years old & is an amazing dog, sweetest nature anyone could hope for but we have to do what is right for her & no matter how heartbroken we are if it is her time then we have to let her go.
