Dogs are often called man’s best friend, and for good reason: they are absolutely adorable, extremely loyal, and quite very territorial. Having one canine companion in your home is great, but if you want to spread the love and have another pet dog in your house, then that would be a wonderful experience for you. You will have a house with two lovable dogs, and they will be there to protect you from harm, but most especially, they will be there to give you love, loyalty, and utmost happiness. However, before you can achieve this perfect harmony with your dogs, you need to go through the process first of bringing a new dog home to your resident dog. And you need to know that this process is not as simple as bring in the new dog and let them both sort things out. Your resident dog can turn territorial and will refuse to welcome the new dog, and the new dog could reject the idea that there is already a dog claiming the property and will become violent. The meeting of your old dog and new dog needs to be smooth, in order for the three of you to get along fine.
