I have a 80 pound lab who's jealous of my 4 month old puppy. I never leave them alone or let them play together (Beau has accidently stepped on Pippin). I don't feed them together and I separate them when I give them treats. I am constantly on guard that Pippin doesn't try and play with Beau's toys. I agree with Yorkiekist, I would not trust the big dog. Small dogs can fight with each other, too, but the large dog can fit the puppy in it's mouth, and seriously harm it.
I would introduce them slowly with something in between. Have the puppy in a pen and let the other dogs see and smell it but not be able to strike out at it. I hope it works out for you. |
