How long can my dog ​​wear the ThunderShirt? Most guardians say their dogs really like wearing their ThunderShirts and can wear them for long periods of time. But keep the following tips in mind: We recommend removing the ThunderShirt every hour or two for the first few times to ensure your pet is happy. That the vest causes skin irritation or other problems is very rare; but it is always better to be careful. And, always remove the ThunderShirt vest at least twice a day if you wear it for long periods of time. What type of training is necessary to use ThunderShirt? There is no training required, just make sure you get the vest on correctly by following the instructions. What if I see signs of discomfort or irritation in my dog ​​when I wear ThunderShirt? With the right size and placement, your dog should be very comfortable wearing the ThunderShirt Vest. Problems are very rare, but if you notice any signs of skin irritation or physical discomfort, stop using it. How to clean ThunderShirt? ThunderShirt is made from durable, washable fabric. It can be washed on a regular cold-wash cycle. Make sure that all Velcro fasteners are closed to avoid the risk of other garments snagging during washing. Hang dry. Is overheating a concern when using the ThunderShirt? Except in extreme conditions (32°C in the sun), overheating is not usually a concern when using the ThunderShirt. Dogs cool themselves mainly through the mouth when panting and the paws. The ThunderShirt is made from thin, breathable fabric. Are there any special size and fit considerations for male dogs? When placing the ThunderShirt on a male dog, the straps that go around the stomach area should not cover or put pressure on the genitals. If ThunderShirt rubs against the genitals, it may cause irritation. If you see any indication of this, remove ThunderShirt immediately.
