My dog is aggressive to other dogs. How can I bring home a puppy?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 2 years and 6 months old | 14.1 lbs

We would like to get another puppy, however our 2 1/2 year old shihpoo started acting aggressive when we visited the dog park and aggressive when we went to see a puppy. How can we get it to work out, both in the dog park and with a new puppy in the home. He use to be really good with new dogs up until 2 months ago...either he is protective, or it's a get out of my face, or he is just insecure. He tends to stay with me in dog parks. Any suggestions?

I personally would not recommend getting another dog for the house just yet. I'm quite concerned that Crosby is aggressive at the dog park and when you went to see a puppy. I would be very worried that he would attack a new puppy, causing it serious harm. The best thing to do is get him into a professional behavioral expert to work on his aggression. I never recommend owners try to deal with aggressive dogs on their own due to safety risks, it's best left to a professional. The professional can work with him and you on his aggression issues, and they can give their opinion as to whether or not another puppy would be safe in your home. Unfortunately some dogs are meant to be only dogs due to these issues, but certainly work with a trainer first before coming to that conclusion. You can ask your vet for a recommendation to one. I hope this helps!

Our dog is dog aggressive. We had another adult dog when he was a puppy. They were great together. Rocky passed away recently. We want to bring another dog into the house. We are very worried about introducing Cody to a new dog. We have been lo
The most important thing is that, if you get another dog, you introduce the two on neutral territory. Just waltzing a strange dog into Cody's house is begging for trouble. You could try a trial meeting to see how Cody is with the other dog. I would recommend a bitch, as two dogs of opposite genders are the least likely to fight. Remember that Cody was there first, and be sure he gets the lion's share of attention. Sometimes, the novelty of a new dog, and the requisites of trainng, mean that the old dog gets left out a bit. The new dog will not know you, and will therefore have no expectations as far as interacting with you. But Cody will want what he's always gotten. I don't know if Cody is aggressive due to basic temperament, or if it's a learned behavior. You can ask your vet for a referral to a canine behaviorist (different from a trainer) to help with this. Good luck!

Jack is a Aggressive when it comes to other dogs when I’m walking him, I am wondering if I bring in a small puppy that is barely wined Would he Attack the small puppy because he is territorial? I want a toy goldendoodle puppy...
Before bringing in another dog to your home, I would recommend getting a trainer to come to your home and work with Jack. We cannot predict if Jack will attack another dog when they come into your home, but you can try to work with Jack and see if you can correct the problem. The trainer will be the best person to discuss if bringing another dog in would be ok. Thank you for using Boop by Petco.

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, I have a male Australian Cattle Dog puppy who is about 15 weeks old. He seems pretty happy and is friendly towards people, but is protective and dominant as well. The few times we have taken him to a dog park, he is immediately aggressive; s
If Hondo gets into a fight every time he's at the dog park it would be best to discontinue going. For some dogs, the dog park is a high-stress place and it may not be for them. Other ways to exercise can include solo walks, fetch in secluded areas, and even focused activities that don't involve other dogs. If he's having trouble with the new puppy, or is severely dog aggressive/reactive it would be best to talk with a trainer or behaviorist in your area that can work with you on a plan to help get him more desensitized to other dogs, and potentially doing OK with some. In the mean time, if play gets too rough or one or both dogs seems agitated, taking a break and separating both dogs until they've calmed down is best. Make sure not to leave them unsupervised together as even the sweetest dog can accidentally injure another! Since aggression toward other dogs is a complex issue, it is best to work with a trainer who can supervise your techniques and plan in person.

It sounds like Bruno has not been socialized well with other dogs, which does tend to make it difficult to introduce him to other dogs. Try introducing the dogs in neutral territory - like a park. If it's not their house, then they will be much less likely to fight. While having the muzzle on does add security, it can make the dog act aggressive. Same can happen if you are holding the dog or putting tension on the leash. The best and safest way to introduce them would be at a neutral place with a fence inbetween them. Let Bruno off lead to explore the other dog. If he's aggressive right away, then it won't work. If he's not aggressive and seems interested, then the next step would be to introduce them while walking on lead or in an open area off-lead. This is a bit more risky, so just make sure you're nearby to break up a fight, but don't be overbearing (i.e. holding the lead tight). I hope that helps and all goes well.

My puppy is 11 months old and he was always very social with other dogs and humans. After having one bad experience with another dog, he is now EXTREMELY fearful and aggressive around all other dogs/ some humans. He won't bite, but he gets pretty clo
This type of behavior is often due to anxiety and is not likely to improve with training alone. I would strongly recommend talking to your vet about anti-anxiety/ behavior modification medication which can make a huge difference! Often times, training is also needed in conjunction to medication. I would DEFINTILEY get that under control before considering adding a new dog to the home. Best of luck to you and Astro!

I'm sorry to hear that you're having this issues! It sounds like there are a few different things going on here with both dogs, which definitely makes the situation more complicated. From your description, I can't quite tell if your male dog's crate aggression issues are directed at the puppy only, or if this is more of a general problem and he also snarls and runs from the puppy at other times as well. This is important information to help determine what may be going on so that we can make suggestions. I'm not sure how old your new puppy is, but if she is younger than six months, aggression at this age is quite uncommon and very concerning. Possessive aggression (also called resource guarding) over owners is a relatively common problem that can often be successfully treated, but you would really need an expert who can help you in person. Particularly in a young puppy, a veterinary behaviorist would be your best bet to evaluate the pup and put together a detailed plan to start wo

Keep Caius away from your puppy at all times. Get him into your vet as soon as possible to discuss a referral to a behavioral expert. I never recommend owners work with aggressive dogs on their own due to safety reasons. Working with a behavioral expert will help determine if this aggression is something that can be trained. I hope this helps.

Hi there! A dog I recently purchased from a shelter has shown aggressive behaviour ( attacking an unprovoked dog) any advice would be great!
That's not good. I never recommend owners work with aggressive behavior on their own due to safety risks. I would speak to Teddy's vet about a referral to a professional behavioral expert for training. Do not allow him off leash around other dogs when you are in public, and don't have other dogs come over to your home until the trainer feels it's safe. I hope this helps!
