At 10 weeks old, your puppy might be still very 'nippy'. I remember when we first got Gucci, she didn't like to be woken up and would growl (especially at my kids, when they would pet her when she was sleeping) I turned her on her back, gave her a FIRM NO and growled back at her, and after about 2-3 times of doing that, she's never growled since. She was very, very young and would nip at us too, but again, I gave her a firm no, and offered a toy or chewy to bite on instead.
If you read through some threads here, you'll notice that some Havs tend to focus on the main caretaker first and are a bit slower to bond with your family members. I don't think that is highly unusual, as many of us have experienced that. Even though, my dog does love everyone now...she definately prefers me!
But I remember the first few weeks we had her, I was very upset that she wasnt' bonding with my husband and kids like I had hoped, but this morning, she fell asleep on his chest and ditched me last night to go play with the kids! So, she has gotten much better at dividing her time up. Right now, she's cuddled up next to me
Some havs do really cling to the main caretaker a bit more, just depends.
As far as the breeder having too many litters? IDK..how many females does she have breeding? Is she breeding the same one again? I haven't heard of that breeder.
Hi Robin! Gucci sends kisses to Cousin Auggie!
