Leaving a 7 months puppy alone

Hi,

I will be away from home for 33 days, My dog will be 7 months.

Its a mixed breed, friendly Puppy with alot of energy, he is deciplned at home but need more eduction for his behaviour outside.

I have 2 questions:

1. Since he is still a puppy, Is there any chance he will be influent badly if I put him in a good place that take care of dogs? (education change, behaviur, fears etc).

2. Is it better that I keep him home with a person the dog doesnt know that will be less time home and will not put time in education like I do?

thanks!

I think there's no problem about it. As long as they will be responsible to the dog when you leave.
