Working the dog doesn’t drive the genetics, the boxer is genetically already a working dog. A non “working line” puppy can be trained to work
Wouldn't it be nice if that was really true!
Not just for boxers for other breeds as well... GSD, Labs, pointer...
Working the dog doesn't drive the genetics. But, genetics (ability to work) do play a part in the breeding from working breeders.
Can a non working line boxer "work".. sure but they are more the exception to the rule.
If someone want to do sport/comp with a boxer why take a chance on a non working breeder?
If what you say was true... Every GSD would be a police dog.
