What is your opinion on Pit Bull Terriers?

I am intrested in peoples opinion and what they base it on.
For those of you who think I am looking for negative responses, I’m not. I have a pit bull who I have raised since he was 5wks old. He is an amazing loving dog and I just wanted to hear why people were so affraid of them.

My “Snickers” is the most loving, people pleasing dog I have ever had the pleasure to train.

So please dont call me ignorant simply because I asked a plain question, originally.

German spitz /Beagle size with Labrador / Rough collie temperament?

I’m looking for small inside breed, not toys like the Chihuahua. German spitz /Beagle size with Labrador / Rough collie temperament.Good choice for a 7 year old … don’t worry I got the pet knowing i would have to take care of !

So I need dog which has less of a tendency to become aggressive/dominant or nervous/frustrated around kids,easy to be socialized and train, low energy but playful, friendly with other pets, dogs, kids and strangers, low prey drives, which doesn’t bark much , easy to maintain, grooming etc…
I was raised around hunting and working dogs, no good experience with small companion breeds.
Thanks and I would like to hear owners or people who work with dogs too.

Temperament of a border collie x rottweiler pup?

I was just wondering what the temperament of a Border Collie x Rottweiler would be, I know since it is a mixed breed you can’t be certain of its temperament but could anyone give me a rough estimate? Also could I have rough estimates for these as well?
Excessive requirements:
Youngest age of child that it could be with: (newborn to teen)
Trainability: (this one I am not really worried about but an estimate would be good)

Thanks!
Sorry, I meant Excersize requirements 😛
