I have a 12 week old Brittany puppy that overall is a great puppy; she has taken to potty training well, learns things quickly, and is very loving.
About once per day though, she gets VERY excited and it is like a switch has been flipped. She starts biting my feet, tugging at my pants, and playing really rough (we work on bite inhibition and she is very gentle most of the time but during this excitement period it is like everything she learned has gone out the window and she is basically uncontrollable). This lasts for probably 20 minutes or so, then she is back to being herself.
When she bites my feet, pants, shoelaces, etc. I take a chew toy and try to get her to chew that instead. She will for a second, but she would rather chew my hand, pants, cords, the wall... again though, it is just for this short period of high excitement.
My question: How should I handle this situation so that she doesn't get so over excited? I know that she is a puppy and they get excited and they love to chew, I just wanted to ask this question because I don't want to be in the situation where I say "She is a puppy and will grow out of it" when there is something I should be doing to avoid carrying this behavior into adulthood. I feel like she just needs a few minutes to calm down, but I don't think I want to put her in her kennel because I don't want the kennel to be a punishment. Is a "timeout" like this a good idea? Any other ideas?
Thanks in advance for any advice.
