We recently adopted a second rescue dog, another dog we call Beau. We did it on the theory that a second dog helps to give the first dog some balance, be more well rounded and less dependent on us. We also opererated on the theory a second one isn’t really that much work. He is a good little dog, 3 years old and housebroken (one of the many good things about mature rescue dogs). We forgot about the stresses that come with fitting a new animal in your life. I am sure a year from now it will seem simple but right now it is a lot of work.
