Been a while as I haven't been training outside of the odd bi-annual sharpening of my old male (8 years).
To keep a long story short my current male has dusted hips, cancer on his lower jaw, but is otherwise moderately active, alert, and with it. When he started slowing down and showing signs of discomfort in the spring I began researching breeders and litters for my next dog. I put a deposit last month on a pup that will arrive in early May.
My question is for those who have raised male pups with strong adult males that were in the late stages of life. What are the do's and don'ts outside of leaving them alone together with no one around? I know it will be a temporary arrangement because of the condition of my current dog (he has six months left at best) but I also want to avoid a situation where I am dog run rotating until that time arrives. Even though the male is old and rusty he is still capable if provoked. He is hit and miss with other males so I am thinking a puppy shouldn't be that much of a problem but I could be totally wrong.
Any wisdom from experience is appreciated.
