Well said Dennis..lions indeed.
I do have to say that I like Theodore's teachable attitude.
Theodore, I have a few questions.
1. How much time does she spend in the crate a day?
2. you said that you are exercising her a lot, that is great!
How much exactly and what exercising are you doing with her...like Connie asked a schedule.
3. Have you started any form of pack structure program like Ed outlines in his pack structure video?
I know she is awfully young, for this....but I'm going to say given her behavior...that we should consider it.
I had to put My daughter's 7 month old at the time Dachshund pup in a modified pack structure program. Dachshunds were bred to hunt badger, and he has a working temperament. No quit or back down in him. He is really drivey and one day it was like someone turned on a switch..he turned into a land shark.
NOTHING WORKED...NOTHING.
We tried all you listed..he was getting plenty of exercise particularly given his age...you have to be careful because they aren't mature in their bodies. I PM'ed a man here that does earth dog competitions and is familiar with terriers and such..Bob Scott.
I outlined a proposed exercise program...he made adjustments and I went with it. He basically upped the frequency and decreased the length. We were doing 4 3/4 mile power walks a day....for a mini doxie.
Anyway We put him on Ed's adult dog pack structure program, but with the addition of lots of play time....after AFTER the social isolation phase...yes with a pup.
He was uncontrollable. We even did the thing where you catch their jaw and curl their lips in over their teeth and squeeze till they yike.
The pack structure program worked really well. He was in his crate in "Isolation" meaning no cuddles or playing for 1.5 weeks.
Then I had her take him out for short play sessions involving marker training and tug and chase a ball.
If he was obnoxious he went back in the crate. As Ed says he lost the privileged.
It became really obvious really fast, that we weren't going to tolerate him acting that way.
IN ORDER FOR THIS TO WORK YOU MUST MUST MUST HAVE A STRUCTURED AND REGIMENTED EXERCISE PROGRAM FOR THE DOG. IF NOT THEN, THIS IS INHUMANE.
Potty breaks were separate, as well as food time.
He is now a reasonably calm pup...as drivey pups go. lol.
I hav also found that he does much better when he is mentally tired as well. The physical wasn't enough.
I like this program because you don't have to physically confront the dog...in our case it was too small and fragile..when a leash correction or firm physical touch won't do it, where else do you go with a dog so small?
Like Ed says it makes it really clear to the dog who is in charge and what won't be tolerated.
Normally in a pup this young, I wouldn't advise this, but if the dog is getting lots of exercise and training and such...it might be necessary.
I welcome input/thoughts!
