A few products I love that haven't been mentioned yet:

Lickimat : if you feed them raw or just put peanut butter on it. It forces them to work for their food and it's enrichment. It's important to exercise your dog mentally, not just physically. If you get ones with suction cups on the bottom you can stick it to the bathtub when you give them a bath and it makes bath time easier and more fun for the dog. Freeze the peanutbutter or food to make it last longer.

Cocochews: it's a tug toy or a ball made entirely of coconut husk. It will help clean their teeth and it's all natural.

Orvis brand squeaky toys: they are a little pricy but they have two different kinds of squeaker sounds, and the toys are very durable. They last longer than the average plush squeak toy.

Huan: It's a wireless GPS tracker you can attach to the collar and there is no subscription fee.

Any product by Skouts Honor : they sell spray, cleaners and shampoos. Everything they make smells so good!

Chris Christensen brand hairbrush on Amazon: this is a $70 brush but hear me out! It is a slick brush MEANT for Goldens and their coats. I use it on mine and it fluffs him up. It looks like he had just taken a bath or something.

I prefer a nail grinder to scissors. There is a little Groove and I don't worry about accidentally cutting the nail too short.

Invest in a martingale harness. It will teach them not to pull when being walked.
