The most important thing is to take this introduction slowly. The more patient you are, the better your chance of success. Do not force the dogs to interact. Once the dogs are able to view each other at a close proximity, allow one dog to walk behind the other, and then switch.
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. If you want a second dog, you need to be ready to commit to this process and not panic.
Expect the dogs to sniff, circle, play, urinate or simply ignore each other. Let them do what they want to establish a relationship — with as little mediation from the owner as possible. If the animals try to fight, it's time to intervene.
The 'Rule of Three' means that you can gauge the time it might take for your dog to fully acclimate to his home in threes: three days, three weeks, and three months. Think of your new dog's first 3 days as their time to decompress as they transition from a shelter or foster home into your home.
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. He may not like sharing his territory, toys, food, resting places, or humans.
In dogdom, there's a turn of phrase called, "Second Dog Syndrome". This describes the process of adding another dog to the home quite well, but not necessarily in a positive light. As humans, we are bound to forget all of the time and effort it takes to raise a puppy right.
It is 100 percent normal for your adult dog(s) not to love a puppy. It's OK for your adult dog not to want to be jumped on or be a chew toy for a new puppy. Dogs aren't programmed to take care of youngsters. Your dog may want to go away from the puppy or may growl or even snap to tell the puppy to go away.
Don't Pick Up Your Dog
The action can trigger a dog's prey instincts, much the same way a squirrel running up a tree might do the same thing. If you must pick up your dog, turn your back to the approaching dog to hide the motion and minimize the chances of triggering an aggressive response in the other dog.
The amount of time each individual pet needs to adjust to their new homes will vary, but the 3-3-3 rule helps give an approximation of what new pet owners can expect. The 3-3-3 rule refers to the first 3 days, the first 3 weeks, and the first 3 months after bringing a shelter animal home.
Bringing home a new puppy or another adult dog can trigger jealousy in your dog, and they may show signs of aggression toward the new addition. Your dog might growl at the new dog, guard your lap, or try to get in between you and your new furry family member.
Most experts agree that, as a rule, male and female dogs get along better than two females or two males.
Let your dogs sniff each other and greet each other normally. Give them positive reinforcement through calm verbal affirmations. After letting them play for a while, put both dogs in a “sit” or “stay”, then let them interact again. Finally, take them on walks together, allowing them to sniff each other along the way.
Your dog is used to being your companion, and if there are other dogs that are taking you away, they are going to act upset, jealous, and even angry. This new puppy is also on their territory, and they may feel like their life is in jeopardy. This behavior is perfectly normal.
The reality is that older pets are likely going to need some time to adjust. They may have some complicated feelings about your new addition—an addition that's sharing your attention. This abrupt change can certainly bring up a wide range of emotions and behavior from the older dog.
Dogs are social animals and usually happier around other dogs, but a second dog will never be a substitute for inattentive, absent or too busy owners.
For example, if you get a new pet and start paying it more attention than your dog, the dog will not feel betrayed in the true sense of the word. However, it may show signs of distress and disappointment because it is suddenly being treated differently or being deprived of something it is used to getting.
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.
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.
When it comes to where dog's get their daily calories, we recommend following the 90/10 rule: 90% of calories from a complete and balanced diet, 10% from treats! Treats can be considered the splurge, but more often, the actual act of giving a treat means more to the dog than the actual treat itself.
The American Kennel Club says changing owners can be traumatic for dogs. Losing their owners can make dogs stop eating, lose weight, lose interest in physical activity, and exhibit symptoms of canine depression. That's why you must take any decision to re-home dogs seriously.
