Had the pleasure of working with Denis over the last week here in Ontario Canada. Such a fantastic experience! His knowledge and skill helped our dogs tremendously. Great guy to work with.

I have to thank Denis a lot, an incredible trainer and instructor, excellent training proposal and methodology, simple, objective.

Denis is an excellent and talented helper and trainer. He reads dogs clearly and has a way of bringing out the best in each team he works with. Denis is also very safe for the fast and powerful dogs. He provides great feedback and insight, plus, he's a lot of fun to work with. I can't wait to work with him again!

From first hand experience visiting Denis I can tell you this is the man. He is everything you see and hear about quality, a man of his word and honourable. His dogs are what he says they are and his clothing is practical and built to last.

We had a great experience from start to finish buying a dog from Venoom. Very easy to communicate with, professional, and got me exactly the dog I wanted — temperament, drives, pedigree, etc. The process was simple and my dog arrived happy and healthy. I couldn’t be more pleased. Will be recommending Venoom to anyone looking for a high quality dog.

We would like to thank for the preparation of our two females ( Hesi Zde-Sko and Jagira Aykmar ) for the championship. Very helpful, always ready to help...
