We are looking for an additional family pet. We currently have a male Yorkie who is 5 1/2 years old who has been fixed. My husband is almost 40 and I am almost 30, so we are pretty active. I stay at home with my boys, so the dog would hardly ever be left alone, except at night when it will be either crated or put into the laundry room with the Yorkie. We live in a neighborhood right on the lake, but we have over an acre of lot that we own, and we have a medium sized fenced in back yard for free play. Our Yorkie is hardly ever on a leash, as he never roams away nor chase the squirrels that run from tree to tree. Our neighbors have dogs also, a collie and a weiner dog. We live off the main street and our house is the only one located on this street, so it is somewhat private. We live in Southern Indiana so we get both cold and hot weather. We also have a 2 1/2 year old and a 4 year old, who both are very gentle with our Yorkie. They enjoy throwing the ball for him, but we are looking for more of a dog that they can really play with and grow up with. We would prefer a dog that's not too big, maybe a medium size dog. I also have two stepdaughters that visit often that are 13, so we need a dog that can withstand new people and lots of loud, playful fun. We would like a dog that can live in our home, but that is has a low shed quality, as we all suffer from some degree of allergies, and my husband dresses up for work. I grew up with Australian Shephards and my family has some and we love the fact that the boys can "wrestle" with them, play fetch with them, etc and the dogs love it, but you can sit and watch their hair float through the air. I will be getting whatever breed we choose fixed, if case that makes a difference. If you need any more information, please feel free to ask. Basically I'm asking for the perfect dog, low shedding, not a yapper, great with kids and other dogs, super fun loving playful dog. I would also like one that is easier to train as I don't want my youngest to always be playing in puppy poo. Our Yorkie is puppy pad trained at night and outside trained during the day. I've looked on the internet a little before finding this site, and a Whippet or American Bulldog looks like they have the characteristics that we are looking for, but I'm not sure. Thanks for any help!!
