Our 19 year old Shitzu has lost her functions, is confused and having seizures. I just got off the phone with our vet and they told me it is time. I am so heartbroken!! She was a rescue dog and was so sweet! I feel bad I cannot care for her anymore, but bathing her four to five times per day has gotten to be too much, she doesn't respond to anything and I feel guilty. Any advice or help?
