My male dog was having a problem with marking in the house. The girl at the pet store told me that this was the best stuff for all problems in dogs, Well she was correct. If I run out the dogs act up. Its crazy how well it works.

My mom's Shih Tzu, Candy, was having anxiety attacks, especially at night. Thunder storms and loud noises bothered her, and sometimes we didn't know what had caused an attack. She wanted my mom to hold her constantly. Those times were very stressful for my 76 yr. old mom. The vet suggested different types of medication which helped at times, then she told my mom about D.A.P. and it relieved Candy's symptoms the best. We could even tell when the refill was getting low by the way Candy acted. The vet charged twice the amount so I searched Amazon. Thanks so much for a great product, and the lowest price we have found.

We have four dogs, and three are males under the age of three. They tend to get feisty with each other, and will often posture over resources (bones, food, attention). A month ago I put the collars on two of them and also put two diffusers in the house. Their behavior improved! Once the D.A.P. expired, they got naughty again. I'm impressed with this product.

Excellent product. The DAP stuff really works. I have a beagle/border collie mix and he seems calmer when I have this in the house.

This works very well for my dogs in reducing anxiety. I put it by their sleeping and eating areas and noticed an immediate effect.
