Cheryl started working with us in February 2010. We have two bloodhound sisters who turned two-years-old in August 2011. Anyone who knows about bloodhounds realizes they are very playful, happy, strong, and STUBBORN! Violet and Vicki are crazy about Cheryl BUT they know that they had better listen to her. Cheryl has worked with the girls on all kinds of issues starting with GETTING THEIR ATTENTION, sit, stay, come, down, etc. Perhaps more importantly, Cheryl has worked with us and our son, Andrew. We were not the best pet owners in that we were too permissive with the girls. Cheryl has been a Godsend for us. The three of us recommend her highly. So do Violet and Vicki!!
