My old dog is aggressive and bites my new puppy. How do I stop it?

Your worry is very valid! It is best to make sure the two are only playing together when you can directly supervise them and that puppy and your older dog are separated when you are away so that an accident can't happen - even the most well intentioned of a dog can cause an injury! If the puppy starts playing too rough, a "time out" of a few minutes for everyone to calm down can also help and teaches your puppy that too rough of play is frowned upon. Diverting with treats and toys is also a great way, so keep that up.

Puppies can sometimes be A LOT for senior dogs and it can take some time for them to get use to one another. If there were any food, treats, toys or special people near by Buddy could have just been acting protective over these. Also, with Buddy being older, if they puppy is always playing, jumping on him, or nipping at him, he may have been just trying to tell the puppy to leave him alone or trying to set some boundaries. Also, if he is arthritic and he knows the puppy jumping on him hurts, he could have reacted to prevent this. I would continue to keep them separate until you know they can be left alone together. I would definitely feed them separately as well. I would be sure you are still spending plenty of alone time with Buddy as he may be feeling frustrated that his home life has changed with the new addition. I would continue to have short but frequent times of them being together. You could also start Buddy on an anti-anxiety chew like composure or composure pro and get him a calming collar like sentry or adaptil. If these don't help, talk to your vet about anti-anxiety medicine like fluoxetine or trazadone. I hope this helps!

That sounds like a tough situation and I hate to hear this is happening. Most humans cannot correctly read canine body language without additional training. Unless you know what the dogs are saying to each other, it's impossible to know how to modify and train the dogs behavior. Canine aggression is a complex behavior as it can stem from dominance, possessiveness, fear, anxiety, resource guarding or a combination. I recommend to work with a professional trainer. This will give you the best and fastest results. Researching on your own will also be helpful. Familiarizing yourself with canine body language and dog training can help you to recognize what your pet is trying to say. You can find many books written on the topic and there is a trainer named Victoria Stilwell who I think is particularly helpful. Best of luck.

If your dog does not get along with other dogs it was probably a very bad idea (and a very stressful one) to bring a new puppy into the house. A new puppy can also be hard around a newborn as they aren't yet sure how to interact with each other. You can try to continue to get the two to get along by starting with limited introductions that are supervised, however if a fight breaks out the interaction should be stopped immediately and started again later. Never leave the two unsupervised together as even a good play sessions can cause accidental injury. You can also use baby gates as a way for the two to "meet" each other without being able to physically be together. If fights are continually breaking out, talking to a trainer or behaviorist that can observe within the home is best.

Hello and thank you for your question. I'm sorry to hear your two dogs are having trouble. Biting behaviour in puppies is very common, but should always be discouraged. At this point it sounds like you'll have to separate the two dogs, at least when unsupervised, for the safety and sanity of your older dog You can gradually start to re-introduce them with close supervision, and only reward the puppy with treats and praise when she is calm and quiet around your older dog. You could even take a step back and have them sniff each other through a baby gate, while giving the dogs treats and praising them when they are calm together. Everyone in the household will have to be on board with discouraging Clara to bite. This means that if she is nippy around other humans, you should give a firm "no" or "ouch!" and walk away or ignore her. If she consistently does not receive the attention she craves when she bites, she will eventually learn that biting does not get her what she wants. I hope this helps, and that your two pups are getting along soon! Good luck!

That is normal puppy behavior. All you can do is keep them separated. You are not going to be able to stop the puppy from doing normal puppy things. I suggest you crate train the puppy and take turns letting him out to run around and crating him. When he is out running around put the older dogs outside (if you have a yard) or in another room so they can get some peace.

it is important to remember that Chico was there first, and is used to a certain level of attention from you. This newcomer has no expectations, so be sure to dote on Chico as much as ever so he feels secure. Then, gradually, you can increase the amount of time you give the new guy (without taking anything away from Chico). The second issue you are facing is that the dogs have to sort out, for themselves, who's who at the zoo. In other words, they may have one order of inportance to you, but they need to determine amongst themselves who's top dog, who's in the middle, and who's on the bottom. There may be a bit of snapping and barking going on, but as long as there are no injuries or serious fighting, leave them to it. Once they get it squared away, everyone will know his place in the pecking order and will (usually) behave accordingly.
