I have used Back on Track products for my three Labradors for many years....I am extremely pleased with the quality of the products, the mesh therapeutic coat, the cool coat, and the heavier coat. I noticed a significance difference when my one Labrador was injured, resulting in a spinal bleed. I used the bed liner and the bed as well for her during that time. She is one who does not like any coat, harness on her but she actually put her head down, wanting me to put the coat on.....I am a firm believer in the "magic" of all the Back on Track products.....Thank you....
