Hi, I am new to this forum. I have a 2 1/2 year old doxie, Mocha. I bought her from a breeder and have had her since she was weaned. She was very easy to potty train and never has accidents. She is sweet, never bites or chews up things and loves everyone who comes into my home. My problem is that she is sooooo hyper! She tinkles whenever someone comes to the door. She barks at every little noise (noises even I can't hear). She isn't happy in a car (shakes all over) and can never just chill. She rarely can even stay still long enough to sit on my lap and I have tried and tried to get her to sleep with me, but when I put her on the bed, she just runs around like a nut until I finally have to put her back on the floor. When it's bed time, I put her in her crate, cover her with her blanket and cover the crate with a blanket and she is very happy for the entire night. I am 70 years old and live in a 2nd floor condo. I must confess that I don't take her out much--she doesn't walk well on a leash and when we do go for a walk it has to be late at night when no other people or pets are around because if she sees other people or pets, she gets very excited and barks and shakes. She has a puppy treadmill that I use quite often for her and she likes that. When she was younger, I thought her behavior was just because she was a puppy, but now that she is 2 1/2, I can no longer use that as an excuse. Any suggestions?
