My little girl(not little any more) turned 13 last Nov. She still can see and hear somewhat, although she has a cyst on the left eye. The vet said removing it wasn't really worth it at her age, as she's be going blind soon. That was over a year ago. She is still eating well(was too well, we had to put her on a diet recently, 2 cups, she's 22 pounds). Before she was eating 4 cups a day. She looks kinda fat. She is now having a little trouble getting around. She has her highs and lows. Some days she runs, some days it's a struggle for her to get up and make it to the food dish to eat breakfast. This morning I watched her step off the patio(2" step down) and she tumbled, loosing balance and the front legs collapsed. She just laid there a few minuites and got up and went to the bathroom. It killed me to see her like that. She also is having trouble holding her urine. She no longer will go to the door and wait, she'll just go on the carpet by the door. Today I have been bringing her out, but thats not always possible. She, up till last year, was always the dog who would go to the door, come back to you, go back to the door...you get the picture. She'd let out a yelp if you didn't see her. Now she usually doesn't bother going to the door. She is also consuming a lot of water. Probably 4 cups a day. She kinda seems happy, she will often come up to you and lick your legs while at the computer, as to say here I am, lets play. She was always a playful dog up until about ayear or so ago. She'd be the one who'd fling her stuffed animal and it would be everywhere, on top of the TV, behind the couch. She'd chase her tail all day. The vet has said her kidneys are working fine, and gave us a 2 week perscription(which we had a year ago, and it worked for a while). He said we should begin thinking about putting her down. When would you say it would be time to let her go?
