What purchases have you made for your dog that has been a game changer?

I have a husky mix who's very chill, but when he got a harness on him he acted like he was pulling a sled in a race. It was insane, and very few things worked for him.

I got a Herm Sprenger prong collar, chatted with a trainer friend, and watched a lot of YouTube videos. My pup took to it really well, and the only time he's ever yelped in pain was when he took off like a bat out of hell after a squirrel. He hasn't done that again ever since.

I don't have to pull hard at all, or tug on the leash to get him to go anywhere either. It really was the biggest game changer for my dog.

I was told by my trainer friend that some dogs don't take to it well though.
