Our Bullmastiff, Dexter, has never enjoyed summertime fireworks but this year’s festivities seemed to be the worst ever. Dexter was pacing and panting and obviously nervous as the neighborhood celebrated the 4th of July. Nothing would comfort him until we tried the Canna Pet Liquid and he was significantly less stressed within 15 minutes or so. It was such a relief to see this. Although he still was weary of the fireworks, he was no longer seeking shelter and upset. Thank you for this product and all the others we intend on trying in the future.
