I first adopted my German Shepherd/Labrador Retriever in 08'. She is a sweet and protective dog in our family. But she is now 3 years/6months, and we are getting a puppy soon (Apple head Chihuahua) straight from the litter. My cousin's chi had puppies, and before that, we were thinking about getting a smaller dog and keeping our Shepherd at the same time. I think a smaller dog is ideal for us because we travel alot, go places alot (parks..etc) And the size is more portable. Yeah, we bring our Shepherd with us sometimes, but drops her off mostly at the dog resort, which could be costly. Another reason is because little brother slightly dislikes our current dog. The reason is because when Sheba was a puppy, they were playing VERY roughly, and left a permanent scar above his lip. Today, he is a very intimidating figure to our dog, but she still looks after him and loves him. We are going to let him pick out a dog from a Chihuahua litter.NOW, I seen many owners with German Shepherds with Chihuahuas on my journey as a pet owner. Sheba is VERY territorial but can be SWEET to human visitors, and a little cute thing she does is look after the hamster when he's in his exercise ball, but today she scared the heck out of the next door neighbors female pomeranian. I understand she was being very territorial. Since she ran out the front door onto the neighbors lawn, where she called HER territory also. But again, The whole family went to a park any of us ever visited, and there were 2 stray dog siblings. One female, one male. She had fun with the Female.They were acting like mother and daughter :3 But, the male, she did not like because he had a humping problem, but besides that, no aggression. My question to you guys is that "Is it the right plan to take Sheba and new puppy to a park/territory Sheba has not been before?" And tell me the stories about introducing your new puppy to your old dog. Thanks!

I have had dogs with all sorts of personalities. Whenever I've brought home a new puppy I have always just brought it straight into the house as if it belonged/always been there and have never had a problem. Introducing an older dog into the house is a little different but most dogs are very accepting of puppies. As territorially and animal aggressive as some of my dogs have been, bringing puppies into the house has never been an issue. My suggestion to you is to have your brother pick out a male puppy. As a rule of thumb opposite sexes have a better chance of getting along as some breeds or dogs can be same sex aggressive.
I absolutely recommend getting the puppy neutered. Besides some behavioral benefits to having him neutered, like he won't be lifting his leg to mark things in your home, there are several health benefits as well. One of those health benefits is eliminating his risk for developing prostate cancer.
