Fiend,
your buddy's dog Dozer looks just like one of my two dogs. My dogs name is Mojo, and she looks the same except she doesn't have the little dark crown on her head, she looks like she has eyeliner on. Where did your buddy get Dozer? I found Mojo in a parking lot when I lived in the Virgin Islands. She was small enough to fit in the palm of my hand, and full of worms and fleas and mange. Nursed her back to health by feeding her with a syringe and milk/water(she wouldn't eat or drink by herself).
If Dozer is anything like her he is a Very high drive dog. She is mostly pitbull, like Dozer seems to be. Dog fighting is HUGE business on the island where I found her. They spend ridiculous amounts of money breeding dogs to fight. It absolutely disgusted me how commonplace it was. You would see Rasta guys with pitbulls running their dogs through the sand on some beaches with big heavy chains dragging behind them. I even found a pitbull corpse once on an isolated and rocky beach that I had snorkeled out to. It had died in a fight. Broke my heart to see it.
Your buddy might want to pay close attention to dog agression with Dozer. Mojo would never hurt a person, but she will throw down at the drop of a hat with another dog. We treated her like a spoiled child her whole life, and she got constant love and attention. At some point however it was like a switch turned in her head and she became dog aggressive. I have no idea why. She is fine with dogs she knows, but a strange dog that tries to be dominant over her is in for an asswhoopin'. She is devastating when that switch gets tripped in her head. They are very athletic, and have tons of heart. They are sweet and gentle around people though, and Mojo is fantastic around my daughter.
The situation now is that I have to keep her tied up, or on a leash, except for night time when I run her with a laser pointer. It's a shame too, because I can let my Shepherd have free reign out here. Mojo had a couple incidents that require her to be kept in this fashion. Since she is so high drive it's a lot of work to keep her happy and get her enough exercise. Dozer will probably be the same way. He'll fill out some more as he gets older, and he'll be pure muscle if he gets exercise. It's pure joy to watch these dogs exercise, it's like watching an NFL runningback do his thing.
I'm only writing this because I had to learn some of these lessons the hard way, and don't want your buddy to have to as well. They are great dogs, but have some special needs. If you challenge them physically you will be amazed at what they can do.
