Sometimes dogs grow up to become well-
behaved and polite members of society…and sometimes dogs do not have their behavior problems remedied so they behave aggressively and they run around town biting people..and they develop a drinking problem…they stay out late or, worse, they become lawyers. Check out this excellent dog youtube channel.
Border collies, poodles and Pomeranians

Well we can’t stand for that. Dogs need to be trained properly so we can trust these furry creatures with our family, friends and enemies that we can tolerate.
Don’t get me wrong. Some dogs have problems with their behaviour and other dogs do not have problems.

Maybe it depends on how they were socialised and at what age.

Conclusion: Dogs that have behavior problems can be trained as long as we find out what the problem is.
Dogs are amazing creatures. So train your dog properly and we will all live happily ever after. So find yourself a good dog training website that gives you all the information you need.
By the way, do you know how intelligent Border Collies are? Amazing little dogs!
