I got this spray for my coton de tulear 3 year old dog. He has had a couple of bad experiences with a groomer and a vet. He now has anxiety when being groomed and sometimes snarls and is a little aggressive. I read the reviews on this spray and decided to try it. Am I glad I did. I even bought a muzzle to use alongside it but I didn’t need it. From the moment I put a couple of sprays on his bandana and tied it round his neck he was completely calm. I never write reviews so I must feel strongly about this. I could clip his hair with clippers and he was like stunned and licked my hand when it went near his mouth. As soon as i finished I took bandana off and he jumped down and started playing with his toys! So no after effects either. I’m so happy. Thank you to the manufacturers.
