My family has only ever had one pet, and that would be our German Shepherd/Border Collie Mix named Max. He is currently 16 and a half years old and very sweet, and I miss him very much, now that I am in Canada and away from him for such a long time. One just starts to miss all the little things, even down to the way your pets smells.
We have two Dachshunde were I live now, and one is named Toodles and is a bit hyperactive and always gets his way. I have decided to go on walks with him since his owners only hold him in the house all day.
But back to Max. With his advanced age, he cannot walk on his own any more. His hind-legs have given out, at first he tried to still use them, but now he has resigned to just let them drag on behind him. I have made a stock of knitted socks for him so that he doesn't rip apart his own feet on the concrete when he lets his hind-legs drag like this, and it works fairly well, preventing injuries.
We have also made special braces for him so that we can hold him upright and assist him in walking. His front legs work just fine, but since he cannot stand on his own or move on his own, he relies on our family members to assist him in his mobility.
This of course also includes signaling to us whenever he wants to be moved around the house, which he does by whining. For larger distances, we have a bycicle trailer attached to a bycicle, and can drive around with him in that way. He really enjoys these rides.
Apart from this, he is still a very lively dog and has no other major health problems.
We often have met people on the streets though that insisted that we are torturing our dog and that we should euthanize him as soon as possible. Some of them even stated that if their dog would be like ours, they wouldn't bother with all the effort and just put them to sleep.
But if you see a pet that looks like this, would you really do that?
