Chocolte lab

Question
I have a 2 year old chocolate lab. he is big as can be and he is the sweetest dog that you will meet but he is either dumb or he just acts like that because he is young. he is the most hyper dog i have ever seen and i take him to the dog park and he is so much more hyper than the other labs out there. and he is much bigger than the other labs and i wonder if he is mixed with something else but we have papers on him that say he is full bred lab. we discipline him on a continuous basis but he still doesn't learn like our other lab. he isn't neutered and he has a large white spot on him is this normal? Any suggestions would be greatly appreciated.

Answer
Dogs vary so much within a breed, even among litter mates.  Some field Labs are as hyper as any pointer.  A large, high energy Lab may come from field lines.  Field competition breeders are much less careful about breeding out markings like his white spot, so he could still be a purebred.  Field Labs tend to be finer boned too.  

Your first step is to get him neutered.  Hyper dogs tend to have hyper parents.  You don't want him passing on his behavior problems.  Likely his parents should have been fixed, but many so called breeders are very irresponsible.  then obedience train him.  The key to most behavior problems is approaching things using the dog's natural instincts.  Dogs see all the people and dogs in the household as a pack with each having their own rank in the pack and a top dog.  Life is much easier if the 2 legged pack members outrank the 4 legged ones.  You can learn to play the role of top dog by reading some books or going to a good obedience class. A good obedience class or book is about you being top dog, not about rewarding standard commands with a treat.

He needs to be kept busy and active.  Once you complete obedience, you may want to look into other activities.  Perhaps even consider field trials.  He may do well in an area he was bred for.
