I am getting up there in rottie years and i have lost alot of my motivation. i love my mommy and daddy and even the other pesky puppies but i am not doing so well anymore. my mommy is curious to know when its time to let me move on.........she sees me every day and how hard it is to walk and her and daddy have to help me get up and sometimes lately i even can not hold my self up to potty anymore. i was on rymadal but the vet said to try not to give that to me cause its like a drug and i dont want ot be addicted to it so now mommy has gotten the healthy hips and joints medicine from petsmart and i have been on this for a month and a half or so and it helps but its not helping as much as it was to start with. i know my kind of doggie life spans are only 8-12 years and i just want to what others think on how to know when its time to let their doggies go and not suffer anymore. or how to tell if they are suffering. i sure love my mommy and daddy and i hate to see them sad.
