So, we resort to kennels. I always visit the potential boarding place before I bring Missy in. Several factors influence my decision whether this would be a good place to leave her. It is preferable for the kennel to accredited, either by the American Veterinary Medical Association, or the American Boarding Kennel Association. But this is not as important to me as other considerations.
Location is important.
I really like a kennel which is not right downtown. If this is not possible, I will ask if there are regularly scheduled walks, where the walks take place, in an asphalt parking lot, or a grassy play area. I like at least two. I ask to take a tour of the place, and if tours are not available, I do not board the dog. There have been some incredible changes in kennels in the past few years, and more are coming.
