Hi there Alisha! I have 2 mini dachshunds.
A black and tan male named Kahlua and a piebald girl named Penny.
Like Sasami said, the most important thing is to do alot of reading and research and make sure the dachshund is the right dog for you and your household. Sounds like you have already done a lot, thatís great!
I bought the book "Dachshunds for Dummies" before we got Kahlua, it's a great book!
Dachshunds are such awesome little dogs.
Here are a few links that I like, too, that describe the breed and personality, etc.
Kahlua was my very first dog ever, and I fell in love! I will always have a dachshund!
They are a wonderful breed!! They are very loving and devoted to their owners, they are a lot of fun.
The big thing with dachshunds is they can have major back problems since they have such long bodies. You have to keep an eye on their weight, because if a dachshund gets overweight it could cause stress on their backs, and be more prone to back injury, thus possible paralysis. Also, you have to be careful they arenít jumping high, jumping off high things, etc, so they donít injure their backs.
They can be very loud barkers. LOL! Another thing to prepare for! Dachshunds donít know they arenít very big, thatís for sure because they have a huge bark.
They are very protective and we call them our security system. They hear anything and everything, and are very alert to their surroundings.
As far as housetraining, my dachshunds got it down pat pretty well, small breed dogs can be harder to housetrain, like my papillon, but all dogs are different. Kahlua and his littermates were trained from puppies to go outside, so I think that could make it a bit easier.
They seem to get all get along fine, too. I also have a papillon, Jasmine, and they get along good. I would think a doxie would get along good with your shi-tzu but I donít know a lot about their personalities to know for sure. I do find that Jasmine and Penny both being females are always trying to show whoís the dominant one, so if you have a female shi-tzu, a male dachshund might be a better playmate.
I hope that I could help!
Good luck and keep us posted!!
Oh, here's a pic of Kahlua and Penny incase you wanted to see.
