No, in most cases, your dog will not be able to wear his or her lift harness for an extended period of time. Many lift harnesses are not fixed onto a dog like a standard harness is and will simply fall off if you aren’t holding them.
Although some harnesses can be left on a dog during the day, it is probably best to remove them at night. It may be uncomfortable for your dog to wear the harness for too long. Additionally, if the harness rubs against your dog’s skin too much, it may irritate it.
