Henk has worked wonders with my chronically stressed dog. Ziggy got so stressed when new people (or even people he knew) came to the house, I stopped having visitors. He also was also often very anxious around me and my house-mate, and would chew and suck the rugs. Henk has fixed this behaviour, so we can now have visitors and were able to buy new rugs! In addition Henk has given many tips on how to deal with outside stressors, and advised us on trying some different calming medications. Additionally Henk has helped advise on diet. Henk impressed me from the beginning in understanding Ziggy and that due to his severe anxiety, certain methods of approaching him just do not work. That is the opposite to some previous trainers I have tried who have wanted me to ''be more dominant, be the leader, correct him'' etc. Henk knows dogs and I would definitely turn to him again in the future if I need more advice. Thank you Henk!
