The better alternative to drugs. Treating anxiety with medication is often not appropriate. Sedatives can help in extreme cases, but usually they have to be given long before the anxiety attack and are long lasting after the event. Daily medication is expensive and there is a risk of unwanted side effects. Thundershirt is effective and has helped hundreds of dogs. There is no risk of side effects and requires little or no time on the part of the dog owner. Thundershirt's patent-pending design applies gentle, constant pressure to the dog's chest, and this pressure has a drastic, calming effect on most dogs. Pressure has been used successfully for years to alleviate constant fear. Examples: Wrapping babies. People who suffer from autism use pressure to relieve constant anxiety. Vets use pressure to calm cattle before vaccinations. Dog trainers use pressure to alleviate various forms of anxiety.
