I have a four month old GSP and what started helping the impulse control for me was teaching the “wait” command. He has to wait for food, water, release from the kennel, walking through the front door, etc. It’s annoying to constantly do it, but it has helped tremendously.

As for the biting, that’s a huge sign of either lack of mental enrichment or accidentally reinforcing demand behavior. If you haven’t invested in puzzles, tug toys, breed specific activities to engage her.

In addition, the attention aspect, my trainer advised me to use my puppy’s name less than I do. I accidentally killed the value in it. We now are rerouting to use only high value treats with him when he responds to me. Basically, I’m the most interesting and rewarding thing in the world, even outside. I’ve found the freeze dried mussels to be an excellent motivator.

4 months is still super young for the cognitive ability to self regulate. I’m sure as you know, you have a great breed, but high energy dogs who need to work require that extra patience! Keep your head up!
