I have an eight-month old toy poodle.She has a very calm, laid-back nature, until she has to ride in a car. Then she shakes, drools excessively, and sometimes vomits, even on very short rides. My vet prescribed an anti-nausea/anti-anxiety medication, and it did help with the vomiting. However, it had to be administered at least two hours before a car ride, and it was not inexpensive. I read a non-fiction book recently called Travels With Casey, about a man who takes a cross-country trip in an RV with his Lab. Casey freaked out during thunderstorms, which is really bad when on the road, so his owner bought him a "Thunder-shirt". First night on the road:thunder and lightning. With his shirt on, Casey didn't even flinch. I was impressed, so I looked up "Thunder-shirts" on Amazon. Actual Thunder-shirt was a bit pricey at $50+ for a six pound puppy, and I'll admit, I was still a bit skeptical about the whole concept. I found the "Mellow Shirt", and the very first reviewer said it calmed her dog to the point of no drooling, no shaking, and no vomiting! This item was also cheaper. After reading many reviews about the Mellow Shirt helping with anxiety about fireworks, separation, and car rides, I decided it was worth a try. When I received it, I let April wear it around the house for a while, because I did not want her to immediately associate it with the car. It fit her perfectly and she actually seemed to enjoy having it on. Ok, after a couple of hours, the test: a car ride of about four miles. My April was a different puppy; for the first time ever she sat up, looked around, even wagged her tail. No drooling, no vomiting, 0 anxiety!!! I have taken her on increasingly longer rides, all with the same result! This simple concept of a hug from a shirt is nothing short of a miracle in my opinion!
