Thundershirts do work and are based on the same principle of swaddling a baby. If a newborn baby is not swaddled in a tight blanket the arms and legs flail and the baby cries. The baby craves the snug security and warmth of the womb. With dogs a tight fitting shirt , Thundershirt or any tight fitting shirt will work to accomplish that same feeling of security. Bella was a rescue very skittish of strangers wouldn't allow anyone to pet her. Her owner was using her in the capacity of a hearing assistance dog. The owner lost her hearing as a result of a medical condition, rescued Bella who took to the job like a duck to water with the exception of her anxious aggression .
Thundershirts can be hot so I explained that any tight fitting Lycra cotton blend will work. So we put a TuTu on her and as you can see in the pictures her entire demeanor changed. From frightened wallflower hiding behind her owner to jumping on furniture and seeking affection from people she would normally hide from.
Incidentally Bella is a Great Dane Basset mix, look at those feet!
