I have two 8 years old standard poodle littermates. Yesterday I brought home a beautiful 9 week old pup. My usually sweet laid back dogs are having none of this, and have barked constantly for the last 24 hours. I have never had this happen before. The big surprise is that the worst of it is coming from my usually very sweet submissive dog, getting right in the pups face and attempting to bite it. Did I make a mistake??? Is there anything I can do to help them accept the pup? I know it's only been a day, but I don't think could take this constant barking for 2 or 3 weeks.

Your dogs are getting territorial. When you brought your puppy home you should have introduced them in a neutral location away from the house so they won't get so deffensive.

Try taking them out together and let them have bonding time in that neutral location.

Also, when ever you do something routine with your dogs like grooming or feeding, do so in the order the dogs came into the home, this allows your original dogs to know they're still the first.

Hope that helps!

Ask for someone to help you take them on walks together. (If they are fully vaccinated) And this will help them feel more like a pack.

Also get them working together for treats. (Sit, lay down etc etc)

Take them into the garden to run around if you can etc.

My two dogs start fighting every now and then if they don't get to go out for a walk or run etc. Also play games like tug of war etc. Some dogs just don't like puppy's. They find them annoying or aggravating if they have no quiet time. Make sure your older dogs gets time away from the pups.

Its the first meeting and so dominance will be the first thing to sort out.
