The perfect dog
Each family has different requirements. Things they need their dog to cope with and also things it’s unlikely that their dog will ever have to deal with. And so there is never one dog that would fit perfectly into every household. We also have dogs with varying drive. You might have a dog who has a high digging drive or herding drive (not always the breeds you might expect!). Whereas some people will need to do much more work with their dogs than others will. Genetics and experiences hugely influence behaviour throughout a dog’s life. So again, this will vary the amount of work and areas in which you need to focus on.
You might love the fact that your dog jumps up and goes mad every time someone comes home. As long as your dog is happy and not worried this isn’t a problem. Whereas someone else might want their dog never to jump up at people. Both of these options are absolutely fine, as long as you are consistent. The people who like their dog jumping up need to manage their dog around people out on walks or visitors who may not want this. And the people who want their dog to never jump up need to be strong. They need to ensure visitors and people out on walks don’t encourage this unwanted behaviour. Neither of these dogs is worse than the other, they can both be right in their respective families.
Some people may desperately need their dog not to pull on the lead. Whereas others (maybe with a smaller dog or where they are almost always free running) might not need this at all. As long as the dogs are comfortable on the lead both of these options are fine. Even though one has had more training in this aspect than the other.
