Well...seems like there is a lot that is fuzzy.

we have 3 dachshunds

Are they toy or full-sized?

full sized

My neighbor's a toy-sized. One of my friends has a full-sized, though. Her name is Gunda and she's built like a draft horse.

I always forget how many dogs are at your house hyjin.....

we had 3, then 2 and now 3 again

Well, once Tiva and I move there will be one in ours!

yep and its a cute puppy too

Yes he is. He is also quite playful.

they all are at a young age. then it drops off as they get old

I don't know...I've had/dealt with some that stayed playful up until they passed....

my dogs arent playful except the new one

The other two just along in years and/or just not the playful type?

years... they used to be playful

Ah, okay. Well, it does happen to some dogs unfortunately.
