Going in circles and jumping when someone comes into the house.
Nakita is three years old now but she seems to be still easy to train. We just taught her to "wait" for her treat and ball. However, we have a big problem with the way she greets people when they enter the house. She goes in circles whinning like she about to cry, won't listen when we tell her no and after she calms down she starts sniffing everyone!
The other major problem: Biting on my 8 year old grandson. When she was a puppy, they would lay in the floor, play, wrestle and Nakita would bite on his jeans etc. We didn't even think to stop it!! Now she weighs about 113 lbs and my grandson weighs about 50 lbs. When he comes in the house, she starts growling and biting on his clothes and shoes. I know she wants him to play but we need to stop this too. Help?
