Hey red (sorry forgot the spelling by the time I got here )....to answer your questions:
What breed is this puppy? When we adopted him they said he was a boxer-mix but as he has grown we feel he has a lot of german shepard in him (I also know both boxers and german shepards are vocal dogs...I think)

How old?
7 almost 8 months old and 60 plus pounds...

At what age was he removed from his littermates?
I can't really say because we rescued him when he was 3 months but the picture from the boxer rescue was from when he was 10 weeks...I think his previous owner got him a couple weeks prior to giving him up.

What sort of training class have you attended with the puppy?
I have done basic training between with my boss who is a vet and knows a bit about training but I know I did a bad thing by not getting him to an actual obedience class soon after getting him...He listened real well from the beginning and wasn't ever very vocal but now he is in his "teen" years and he is extremely vocal and can be aggressive towards me when we play...I do have his beginning obedience classes registered and he will start in early September...I know I know, shame on me for not doing it sooner right?

Where does this puppy live when you are at home?
When I am at home he has most free roam in and out (doggy door) but if he misbehaves or gets too excited he goes in his crate, 9 times out of 10 if he's gotten into something he shouldn't have he puts himself in the crate. He is a very good dog...when HE wants to be.

When you are not at home?
In his kennel-or his "bedroom"...when he gets excited we tell him to go to his room and he goes in the crate and rests until he's better.
How is he confined when he is outdoors?

How much exercise does he get in a day?
He gets a morning walk every morning around 8am, we have a super large yard he plays in with me during the day and then I walk him in the evening after dinner when possible. I understand that pups and dogs pent up energy when not exercised and because I know this he gets A LOT of exercise, it's the only way he won't act obnoxious. He does really well if we have to leave for a few hours and really well when we come home, he doesn't jump or bark. But when company comes over its a totally different story-I dread company. I don't know if he's consciously fighting for my attention or if he's really excited to see people-he only gets crazy when males come over? Coincidence maybe?

I have been trying to do as much training as I can before his classes start but I don't think it's sinking in because I don't think he thinks I am Alpha, ya know? Now when daddy is home he is on his best behavior and only "talks back" to dad occassionally-usually when he wants to dance or shake a paw. How can I gain my control back? It is really frustrating not being the Alpha or more importantly when your dog thinks he's Alpha-I think thats the main problem but would love to hear what you think. Am I a bad pet owner?
