have you thought about a pug? they are great with kids. they get along well with other dogs, too. i think a GSP would be a great family dog. they can knock kids over with their size and excitement, however. if you get a puppy from a breeder you can choose a calm one. it will still be plenty lively. now i've never owned a chihuahua but i've heard there are better breeds with kids. chihuahua lovers don't shoot me!! i agree with minniyar about getting 2 puppies at once. i would get them one at a time several months apart, for all the same reasons.
I would start with the GSP. After a year, when the dog is fully trained and feels secure in your home( it has had time to bond with you) opt for a sturdy small breed. Not a Chihuahua or the Dash. These are not very baby friendly. It isn't that they will hurt the baby, but babies are not the most careful of people and may hurt the dog. In turn dog protects itself and now your baby has a bite mark on its face. If you like very active dogs maybe a Jack russel or another type of terrier. They have a lot of energy and most are fairly sturdy.
Ok I had to jump in here on the chihuahuasa defense. I have Daisy Dogs and Chihuahuas and find my Chihuahuas are great pets. I really believe it is all a matter of socialization. Chihuahuas do great with all my kids even the toddlers, but of course they were raised together. i have one chihuahua who is timid and meek as a mouse and one who likes to run and play, but never have they been mean or barky. I would say the only time they bark is if they want to go potty or sometimes they get lonely at night and then I bring them from the livingroom bed they have into my bedroom and they are fine. If you socialize well from the beginning with petting and snuggling and baths they usually do fine. Not to mention the fact that if ANY dog took a snap or mean attitude to me I would much rather it be a chihuahua then a big dog. the little ones you usually just have to sccop up and reprimand if there is a problem. No way am I scooping up and reprimanding a big dog who's growling at me!!!!!!!!!
Hmmmmmmm well maybe you have a point but I'm thinking it can go two ways. A toddler can aggrevate a bigger dog as wel as a small dog and the damage could be much worse with a big dog who gets aggrevated. You just always have to watch toddlers closely no matter what type of dog you get!!!!
I have a mini dachshund, she will be 7 years old in November. Lucy is laid back and very loving, I've never seen her hyper. About 4 months ago we came across a lost chiauau and brought him home until we found where he belonged and they hit off, so much that if we hadn't found who he belonged to we were going to keep him.
