Tried everything my dog is happier and better behaved in the house and on lead, yes there’s still slight pulling if just using the ring ontop but if I take into consideration the breed Viszla highly energetic breed that wants to also sniff and being only 2 then yes I now let her have a longer lead an sniff with that much less pulling and not as obsessed about squirrels. Because she happy she doesn’t need to pull the same, never again will I use a halti or slip lead recommended by various trainers, this just yes stopped pulling instantly but not actually found out the problem my dog wanted to discover the world, sniff, be a dog so if you want a happy dog get this! I’ve tried lots of different expensive harness this is by far the best fit and doesn’t rub or pull her leg back with the d ring. Hope this helps get it you won’t be sorry nor will your doggy!
