We adopted 2 English Bulldogs at the end of August @ 8 weeks old. They are brothers from the same litter. We also have to 2 rescue dogs. One is a German Shepard mix and she is 5 years old. The other one is some kind of terrier mix and he is 8 years old. We also live on 10 acres so we do have the room for 4 dogs. We knew our 2 older dogs would not be very excited about us bringing a puppy home. So our thought process was, lets get 2 and they can keep each other company. They are now almost 5 months old and the best of friends. They slept through the night from the very beginning, which was a blessing! They do almost everything together, they play and wrestle all the time and even cuddle when they sleep. But Im not going to lie, some days we are like "WHAT THE HECK WERE WE THINKING"! But I think anyone raising a puppy, says the same thing. Overall, I think we made the right choice. Our other 2 dogs have even accepted the puppies and sometimes they all play together. The only Con would be, the cost of everything they need, is doubled.......Vet appointments, shots, dog food, collars, leashes, training classes and so on.
Hope this helps!
