Dogs are inherently social animals that live well together in groups, but that does not mean that all dogs get along. Most dogs will welcome a new sibling, but it is not always smooth sailing. The furry family member you have now will face many changes when a new dog enters the picture and may feel a bit displaced.
Many people do not give two dogs time to adequately adjust to one another before deciding that having two dogs will simply not work. It can take up to one month for an old dog and new dog to really settle in and accept each other's position in the pack.
Sometimes, two dogs cannot live together after fighting. This doesn't necessarily mean you need to rehome them, but it does mean keeping them separated for the rest of their lives. As we discussed above, you'd need to crate and rotate (using either literal crates or rooms) or split your house into two parts.
It's better to prevent them than to have to stop them after they occur. People and dogs can become injured when there's a fight. Also, a dog will remember that he's been attacked. It may be very difficult–if not impossible–for them to get along afterwards.
Some have recommended that the dogs not be anywhere near one another for at least 48 hours following the fight, even if they live in the same household, while others recommend that getting a positive interaction between the two animals as soon as possible is the best course of action -- at the end of the day, however, ...
This is when you see one dog trying to engage another dog in play, but the other dog is ignoring that dog by looking away, walking to a different play space or flashing their teeth at the dog. These are all signs that at least one dog doesn't like the other. If you see this behavior, move the dogs away from each other.
Second Dog Syndrome
As humans, we are bound to forget all of the time and effort it takes to raise a puppy right. All too often, a second dog joins the household and the expectation is that they will behave as the existing dog in the home does, so they are often given the same freedom right off the bat.
Many breeders recommend that your first dog be at least one-to-two-years old before you add a second to the family. If you have an old dog, they may not be physically able to play with or tolerate a pup.
Introduce on neutral territory.
At first, walk the dogs at a distance where they can see each other but are not too provoked by each other's presence. If the dogs are not showing any negative behaviors, reward them with treats just for seeing each other.
Break the fight up quickly and calmly, redirect the dog's attention, take them for a walk together, and don't worry that it's going to happen again. They may or may not fight again, but if worry over it does not become your obsession, you will not be feeding them negative energy that will lead to another fight.
Just like human siblings, dogs sharing a household will frequently fight over resources like toys, food, treats, or cuddles from their favourite people. Hormonal changes might also be the culprits to fighting – this is especially true if they are of the same sex and one of them is sexually maturing.
By nature, dogs are social and thrive in group environments. Therefore, there are many advantages to adopting a second dog, such as: They can keep each other company. Both dogs will be able to entertain each other and get exercise together.
After getting a new dog, you may find that they quickly become jealous after you bring them home. Finding a new forever home can be a very emotional time. Sometimes, a newly adopted dog becomes jealous because they crave your attention, touch, and voice as a comfort during this time of change.
Many people are hesitant to adopt a second dog because they assume it will be twice the work and twice the money. But the truth is, owning two dogs doesn't have to be more work – in fact, it can often be easier. And as for the cost, it will cost more money than one but not twice the amount.
Now that each puppy can be away from their sibling and has their training basics down pat, you can reinforce their independence by treating each pup as a separate dog rather than as a single unit. Feed them separately, take them on separate walks, play with them separately, and take them to the vet one at a time.
The (sort of) good news is that all these feelings are common. Type “second-dog guilt” into Google, and you'll see how many people feel conflicted about adding another dog to the pack. So though it doesn't necessarily feel good to feel this way, at least there's safety in numbers.
Dogs in the same household can become aggressive toward each other for a variety of different reasons. Aggression may be dominance-related, territorial, possessive, or caused by fear/anxiety. Some dogs have “alliance aggression”.
Many common behavioral concerns, including fear, anxiety, and frustration-related behaviors, become more evident at social maturity and can underly an overly aggressive response. The younger dog may be initiating confrontations to gain access to resources, though that is just one possible trigger.
It's a fact of life. It's the same for canines: Not all dogs like all other dogs. “We have a whole spectrum of dogs,” says Dr. Sharon Crowell-Davis, DVM, DACVB, professor in the College of Veterinary Medicine at the University of Georgia.
There are a variety of reasons dogs may show sudden aggression towards each other. Some of the most common causes of conflict between familiar dogs include frustration, illness, and resource guarding. You'll need to clearly identify the root of the problem to restore household harmony.
Remain Calm and Avoid Punishment
Dogs are highly attuned to human emotions, and reacting with anger or aggression can escalate the situation further. Avoid shouting, hitting, or punishing the dogs involved in the fight. Punishment can lead to fear and anxiety, potentially exacerbating future behavioral issues.
Dog fights are a very dangerous thing to try and break up alone. You should never rush in and try and grab the dogs to pull them apart. They are in high "fight drive" and are not thinking clearly when fighting. If someone grabs them, they will bite without even thinking about who or what they are biting.
