Have two GSDs and what a nightmare and embarrassment taking them both for a walk. Have tried different collars and harness but with limited success until a friend recommended the Happy at Heel harness so after some research and trepidation I ordered one. After fitting the harness the change in my dogs behavior was unbelievable. No more pulling a joy to walk her again and have just ordered a second for my other GSD.
I received this harness with skepticism as to whether it would work, my bull mastiff is a puller but from the word go she walked by my side and I think she enjoyed the walk as much as I did . Would recommend this highly and I will be purchasing another for my other bull mastiff.
