Can a 15yr old dog, mix with a new puppy well?

Let your Labrador Retriever live out the rest of his life in peace, with out another dog invading his space and irritating him to no end. A senior canine doesn't need the added stress of a new pup and/or dog intruding on his territory. Wait until he passes on to bring a new canine companion in to your home.

It really depends on your older dog, how well behaved and sociable he is and how you are going to bring a pup into the house. You couldn't leave a pup unsupervised with an adult dog regardless of how gentle he may be, so you need to consider a crate, crate training etc when you are not there and until the pup is old enough , toilet trained and obedience trained before you would consider leaving the pup while you are at work.

I have several dogs and they are all used to pups coming into the 'family' but I would never leave a pup unattended with any of them until it was 6 months old or so. Pups have a habit of playing and pushing their luck and one attack from a fed up adult dog can kill them or certainly course them damage and in need of vet treatment.

My eldest dog was 16 when I got my youngest who is now 2 years old and my eldest was a great teacher for her and within weeks they could always be found together walking in the garden, laying in the bed together etc and a year ago I got another pup who I was training as a disability service pup for my niece and she was brought into a home with 13 dogs at that time and 5 of the dogs were over 15 years old, it would have only been my eldest two (17 &16) who would tolerate her for very long although she was a very gentle natured pup...but pups will be pups and of course she had lots of other younger dogs to play with..........again she was crated when I was not home for safety. It often gives older dogs a new 'spring in their step' which is lovely to see.

If you are prepared to put the additional work in that is involved in getting a young pup and have the crate available, puppy pen or stair gated 'other room' so your adult dog gets the peace it also needs then go for it, or of course you could adopt an adult dog, it will still need some training etc and at least you can see what its temperament is likely to be and get a calmer natured dog, with less energy level which could suit your family

My 9-year old Yorkie mated and his son came home when he was 4 months to 10 years old. I couldn't leave the puppy alone but I tried very hard to and made Hippi aware that he was still No. 1 dog for me. I don't know if I did the right thing or he knew that it was his son, or it was simply his good temperament that made it work. It worked very well.

Four years ago my two-year old Peke was getting a little lonely and I got him a Cocker Spaniel puppy. They get on well.

All male dogs in both cases. Vets say that a male and a female would be better though.

It totally depends on you. In many instances bringing a new puppy in with an elderly dog puts new life into the elderly dog. However, you will need to have a place for your older dog where he's not constantly being mugged by a puppy. The pup won't have any respect for the elderly dog, and could, if left to do this, make his life a misery. I've said many time before here, adult dogs won't normally attack a puppy to the point of injury. But if pushed far enough, this might well happen. Get a crate for your puppy, if you don't have one. Have him somewhere each can see the other - I'd have a crate, and a room with a babygate across, for the puppy (crate) and the older dog (room). Obviously they will need to be able to be with each other, to get used to each other, but the moment you see your old dog (and at 15, he's very elderly, for a Lab!) is getting upset, stressed by the puppy, you will have to split them up.

However, having said all that, at the end of the day only you know your dog and how he's likely to react. And to repeat, he is very old so maybe it might be kinder to wait. The last Basset of my own breeding was 10 when we unexpectedly really, lost his sister. He was totally at a loss, being the only dog he'd never been before, and having been especially close with his sister. We got him a new friend, and although he didn't actually ever play with her, the problems with unprovoked aggression towards other dogs we started having with him stopped and he seemed much happier to have another one in the house.

It can. My dads dog is 16 now, he's fine with my 13mo dog. My dog is well behaved anyway so doesn't bother him too much. Depends if your lab is OK with dogs.

But, my dog only visits my dad with me occasionally so they're not always together but always get along when they are. Just wait.

Do you want a new puppy to keep him company, or to replace him? I'd wait. Your 15 year old Lab will be fine by itself.

Why would you do that to an old dog? How would you feel if you were a grandma and you were locked in a house with a toddler all day?

Get an adult dog.
