Just to share my experience on taking care of my old pooodle.
I used to have a toy poodle but had pass away last dec. I have keep him for 16 years. Before he have the problem of standing/walking, he already cannot hear, and one eye is blind.
As for my poodle, a year before he died, he already cannot walk/stand proberly, i did buy him subplement from the vat for his bone.
At the later part, he totally can not walk. So when he want to urine, he will bark or move his leg to alert us. Then we will just carry him to the newspaper and put him in standing position.
We also put cloth on his bed, if he urine there then we will change the cloth (just like changing baby pamper).
At that stage, although he can not walk , but he is till a alert dog, he till eat, when i come back from work, he will welcome me, he like to be sayang .........
Later part, he start not eating much or evening eat lesser and lesser. Most of the time he will be sleeping. First thing i do when i reach home, i will carry him to tell him i am back (as he cannot hear anymore).
Because he do not eat, he loose a lot of weight, and the vet ask me to try to feed him liquid food (inject to the mouth) and the doctor also inject some vitamin for him. He used to sleep on the floor near my bed but at the later stage i let him to sleep on my bed becasue i can sense he may just go to sleep and never wake up.
But 2 week later, he "fa yang dian" when i was working. When i rush home, he already like half died. i rush him to the hospital, he died in my arm.
My mum told me, the dog is waiting to see me, before he died.
Please do not be discourage after reading my story. The aging dog may cause u alot of medical fee or time to take care of him. But if u think the dog is part of your family memeber (not just a pet), you will really want to try all out not giving up easily (like put dog to sleep).
THE DOGS NEED US MOST WHEN THEY GROW OLD
I heard from a friend that for poodle it is common to face leg problem when the dog go old. As for Jack Rusell is skin problem.......Different type of dogs will face differnce difficulty when come to old age.
