I have recommended this product to every dog owner I know, including my brother. My brother has a rescue dog named Roman. A high energy border collie mix.He is only about 3 years old at max and came from an abusive home. His anxiety can cause him to act out. His true nature, once calm and settled, is a very sweet, athletic dog. The use of Canna-Pet along with his daily prescription from the vet, has helped Roman feel more comfortable in his skin. He kennels well now, he is still able to be excited yet doesn’t seem to “lose himself” in his excitement. It has been an absolutely wonderful experience for him! He has always been a happy dog, but the difference in him now is truly amazing. He can still be himself, but seems to be able to think things through now a bit, if that makes sense? ha!
