How do I prolong my dog’s life?

I have a boxer, and love him more than life itself. He just turned 2, and is fairly healthy. He has mild allergies, and seizures which are finally getting under control. I try to take care of him, with regular vet visits, vaccinations, flea/tick prevention, and heartworm medication.

How do I prevent him from getting something serious like cancer, like many boxers do? I feed him Acana, and give him plain organic yogurt, brewers yeast, a multi vitamins with b added, and fish oil for neurological support. What else can I do to keep him healthy?

How can I get my dog to listen without using treats as a reward?

My six month old Siberian Husky mix is very smart, but he can be stubborn. He will listen 100% of the time if I have food in my hand. I want to get him to listen without using a treat as a reward, but he just wont listen.

I have tried praise, like petting and saying “Good boy, Akino!”. *My dog’s name is Akino
But he just gets too excited and he will bite, almost like he thinks we’re playing.

Any advice is appreciated. Thank you!

How long can a dog or 5/m old puppy sleep undisturbed?

Its Summer and i don’t have a job or summer school and my social life is just barely noticeable so i have a lot of time on my hands for a few months.

Today i wanted to watch Pacific Rim so I snail-pace walked my puppy outside at 11 morning for nearly 2 hours (1 hour more and walked slower then usual), from the park, to even my old elementary school to make sure he was tired enough to avoid destructive chewing then before leaving i fed him. I can trust him to not pee on the carpet or furniture since he can hold his urine for up 6 hours. (not that i forced him to, it was that one day we took him with us for a visit grandma because nobody will be at home to take care of him.)

After the walk and movie (it was awesome by the way) i came home and there he was happy to see me, he jumped around me for a few seconds then plopped back to his favorite sleeping spot near the window and started sleeping again. I left at 2:15 and came back came back at 5:00 and he’s still sleeping even now at 7:00PM, thats like almost 5 hours, usually after walks and play he naps for about 2 hours then runs around the house and sometimes humps the bed/blanket because he’s so untrained and hyper.

This interests me, how long can a dog or 5/m old puppy sleep undisturbed? I’m not concerned about his health, (he’s perfectly healthy, just untrained/disobiedient), I’m just a little curious about a dog’s sleeping patterns
