I aquired Peanut in August of 2005.
I have two other dogs, both Carine Terriers, named Dodger and Skeeter. They're brothers and both 7 years old.
Dodger is the dominate dog in the house.
When I first introduced Peanut to them, alot of whiffing went on but everything seemed fine. There were a couple demonstrations by Dodger that he was the 'alpha' male of the house. I didn't scold Dodger as I just marked it up as them working out their issues themselves (although always supervised as they're my shadow while I'm home).
It's been a year. Skeeter and Peanut are best buddies. At times you'd think Daytona was taking place in my home from them chasing one another.

- Peanut more or less avoids Dodger, no doubt from a couple comfrontations that occured.
Anyways...
Peanuts stubborn. He knows where the gallon jugs of bottled water are and has no problem getting me to fetch him some. He's too smart for his own good.
Now having the two older dogs, I was concerned about Peanut picking up the behaviors each of them have that are least desireable. He has picked up the selfish/no sharing of toys. There must be 400 tennis balls and chew knots here (literally looks like PetCo exploded in here) - The only one of interest is any that are in use by one of the other dogs. (typical though

)
I'm having one hell of a time house training Peanut. Dodger and Skeeter are fine. They'll come tell me when they want to go outside. Peanut on the other hand.... I take all 3 of them out at once. When either Dodger or Skeeter want to go out, it becomes a family outting.
Now I witness Peanut doing both #1 and #2. However, shortly after coming back inside, I turn to see what he's up to, only to catch him tinkling again. (arggh)
Now when I'm not home or sleeping, he's crated. He's NEVER gone in his crate. Ever! First thing we do when I wake and come home from school/work, it's time to go outside.
He'll do either or both everytime we go out. Yet if he has to go, he'll go find a spot and let loose. But I fail to see where this extra is coming from (lol) - He's just itty bitty. -- And after having just gone outside!
For a positive reinforcement technique, when any of them do their business, those that did 'make' get a treat when we come back inside. Those that didn't, don't.
Anyone have any suggestions? Ultimately I'd like to not have to crate him at night. Dodger and Skeeter sleep under the bed (although sometimes I'll wake up to find one or both next to me in the bed (which is fine with me) - But I cant let him loose as he'll have an accident; no question about it.
