For the same reason teenagers can float and 80-year olds can't. Older dogs just don't have the energy.
Yes, a young dog can learn from an older dog. the young dog does not have to be young. just younger than the older dog.
Yes
One of the reasons that that dogs hump each other is because of dominance. If once dog can hump the other it is dominant over the other. So if your young dog is humping your older one, the young dog is claiming dominance over the older one.
formula if they are very young, dog food if they are a bit older
Puppies mature quicker when young, and slower as they get older..
I'm not sure, but i think it is because the older dog has a lot of protein and the younger dog needs more, because there is less in the dog's system (just a guess)
Yes. but only if the cat and dog grow up together. They don't do well if the dog is grown and the cat is young. older cat and young pup is probably fine.
It actually should be less aggressive, but if it is an older dog it will probably remember more than it would if it was young.
Its really fun well it depends if its a little pup or older i wouldn't know if it was older but if its a little pup than youll have a lot of fun but make sure to try to train it as much as possible while its young than it will be a nice dog when its older
because young dogs learn better than the old dogs and it is always good for dogs 2 learn young
Because the German Shepherd Husky mix is not a pure bred, no one knows the temperament of this 10 yr old female dog. I am assuming that you have the young male dachshund. if your young dachshund is still a puppy and loves to run , jump, play and dig, then he may be too hyper for the old gal. Usually an older dog would not get along too well with a hyper young pup, but if you know a lot about dogs and can handle the situation and protect the older dog and the younger dog from pissn each other off, then it could be done. If the older dog has been raised around younger dogs this also may help them to get along. Normally older dogs dont like to be bothered by they hyperness of the young.
Start young with a fresh mind! Its harder to obtain knowledge when you are older.
