Absolutely brilliant. We fell for the ‘big brand’ names for a harness to begin with which just aren’t suitable for our dachshund at all, and are restrictive. The perfect fit model was suggested on multiple occasions by puppy coaches and we decided to get it. It’s a bit of trial and error trying different pieces but that’s expected for a sausage dog as they’re so specifically shaped! Perfect Fit allow you to try different sized pieces for free then you just send the pieces that don’t fit back. I can already see a marked difference when our pup wears this compared to others - it’s comfortable, easier to manoeuvre even if he is pulling, the harness latch is in the right place around the body so you’re not straining the neck of your dog, and I love that I just need to order a couple of extra pieces as my puppy grows into his adult self. Great customer service, quick delivery! AND the best part is you’re supporting a small business over the giant corporates. 10/10.
