Do you travel a lot? Does your work require you to be at the office 12, 14, 16 hours a day? That is a long time without a restroom break? We ask our pet to hold it that long day in and day out. The other alternative is to leave your pet outside all day, which might not be a bad thing until that thunderstorm rolls in. Ideal pet door has a solution for you. You may not want to give your big dog the ability to come and go as they please which is understandable. However, you may consider installing it in your garage door or utility room door so your pet has access to a dry and warm place to escape harsh weather. This dog door is simple to use and operate making it the ideal pet door.
