My motto is "what is best for my guest dog?". Making them comfortable as possible and quickly helps them to adjust a lot easier. That could mean taking a leisurely stroll around outside letting them sniff and become familiar with new smells to letting them run around inside or allowing them to chill in their cage. I work Monday - Friday job Medical conditions are no issue here. Having worked in several different boarding facilities and also at a vets office I've dealt with many different medical conditions. Behavioral issues ie food aggression or toy are not a problem as long as they are not severe. Food aggression the guest dog will be fed separated from everyone but with me present to make sure is eating. I LOVE my old dogs. They bring wisdom and knowledge to the house. Teaching younger dogs manners to just willing to relax and demand your attention. If you have any other questions feel free to ask.
