USING FOR EXTENDED PERIODS OF TIME: ThunderShirt is designed to be safe to leave on for extended periods rnof time when appropriate for the situation or issue. When sized correctly and properly put on with a soothingly snug rnfit, your dog should be very comfortable. If your dog will be wearing a ThunderShirt for more than one hour at a time, rnwe recommend removing ThunderShirt every one to two hours during the initial periods to check for any signs of rnirritation points. Irritation points are very rare, but it is best to be cautious. After confirming no irritation points during rninitial uses for extended periods, we recommend that you still remove the ThunderShirt at least twice a day for rnthirty minutes. CHEST STRAPS SHOULD BE LOOSE AROUND NECK: Use the two-finger collar rule when applying the neck rnstraps (i.e. easily slide two fingers between the neck straps and your dogs neck without pressure). The neck straps rnare only intended to keep the ThunderShirt in place.
