As you've already noticed, most dogs love the company of other dogs. That's because they're born into litters and surrounded by their siblings from birth. But some breeds are social even by dog standards, and the Beagle is one of them.
Beagles were bred to work closely with people and other animals. This hound's job was to remain alongside hunters who often had many dogs. The Beagle learned how to live, play, and work well in this social and cooperative environment. Even today, Beagles are often happier in a multi-pet household, and can suffer separation anxiety when left alone for long periods. That's why many Beagle owners consider getting their beloved pet a Beagle companion.
A few things to consider before you become a two-Beagle home:
Timing: If you already have a dog, wait until he's matured before adding another puppy to your family. Training two puppies at the same time can be difficult. Plus, it takes a dog more time than you would think to become fully integrated into the family. A safe interval: Wait at least two years before bringing a new dog into your home.
Bonding: If you don't have enough time to spend with your dog, it's unrealistic to think a second dog can fill in the gaps. While Beagles are social creatures and most love to play with other dogs, your dog will still need human company and his daily walks with you. You'll also need to spend one-on-one time with your new dog to bond with him and train him.
Expense: While two dogs can absolutely be twice the fun, it also means double expenses of food, veterinary care, and grooming. You may also have to factor in twice the barking (and for Beagles, that can mean a lot of barking!) and the increased bill for boarding when you go out of town.
If you've considered all these factors and believe that you're ready, willing and able to love, train, and care for a second Beagle, terrific! If you're not sure, it's probably best to postpone that second dog until you're confident you can provide the attention he will need.
