I've got two of the rascals, best little dogs I've ever had. For general info of perspective buyers, BT's are house dogs, NOT outside dogs. They don't have any fur to protect them from heat and cold. They cannot survive exercise in the heat, so these are not jogging buddies. They have great energy for short spurts but don't overtax them. They will literally go into exhaustion or death if allowed. They are not dog park dogs, i.e. don't expect to take them to the dog park and have them get along. They are not afraid of anything and will attack much larger dogs. They shed.
Now for the good part, they are outstanding with kids and other people, they will make you laugh at their antics. They are like little kids. They can tear a stuffed toy apart in about 10 seconds. They fart. They will want to sleep in bed with you and you won't be able to resist, and they WILL fart under the blankets, but they are warm. They are extremely smart.
We're not buying from this breeder but we are picking up a new puppy at the end of this month. That shows you how much I like the breed.
If you want more info, a good website dedicated to BT's is http://woofboard.com. I wouldn't generally post for this kind of subject but I just wanted everyone to know the scoop. I have no association to the OP.
