Dogs intelligence

like T-bob said genetics is really what it is and instinct is a part of genetics...intelligence has to do with genetics...they say a dog doesn't really think it is more instinct but some dogs seem to know when to roll out and when to sit back while the other dogs hunt but this dog will strike first 9 out of 10 times...and this dog doesn't work all the tracks but cuts and slashes and lines out the feeding tracks pretty quick while the other dogs are still working out the feeding tracks...it is genetics but a higher level of intelligence...I have only had one dog that good but quite a few others that were excellent hunting dogs just didn't have that little extra that that dog had...
