Your dog is on the way to not dominant but dangerous behaviors. Please find a positive trainer and get on this immediately.
Some VERY good basic training including leave it etc
EDITED: OKAY, I just realized this is a TINY puppy, supposedly born May 5 but tiny and may be only 9 weeks old, not 11. Puppy tantrums not abnormal, especially since it is likely this pup taken from litter way the hell too young. So panic mode off, you need to work fast and hard on the behavior. I'd say at his size, carry a towel and wrap him up in it til he settles down during an all out tantrum if you are out. Otherwise, at home walk off and ignore. Give attention and praise when good. You don't want to get heavy handed over pretty normal puppy behaviors, you want to gently guide him to good. But I also seriously would not be out walking with this pup til all shots are done. His very tiny size and age puts him at risk.
Thanks Debbie. I've been holding him to my chest when he has his fits (gently) until he sighs and then he seems to have calmed down. I'm really confused with the advice I've been given. When I took him to a park right by my house and walked him for 5-10 minutes I was scolded for not walking him for an hour. And now I'm told I shouldn't walk him at all… what's the right answer?
Yes, walking a baby for an hour, um no. I think others were confused as I was about the age. Lots of in home play time, starting basic obedience at home to keep mind happy.
So everyone thinks he's not 12 weeks? How come the vet hasn't said anything then?
The vet asked me his age. I gave her Basil's papers from the breeder and she seemed satisfied with that.
Can you post a recent picture from the last couple of days of him? And what his age is supposed to be? And the Vet if they looked at his teeth should be able to "estimate" age… but might be off by a week or so.
Again... I take mine out as soon as they have had one set of shots, again using common sense on where I take them and what they can "sniff" along the way.. and as already stated... I don't believe in living in that glass bubble.. but to expose them (using common sense) to living... and building their immune systems. And I have had a number of pups that I have done this with either living with me or puppy buyers
