I follow strict, detailed instructions to ensure the comfort of the animals in my care. My own home is totally open excluding my spare bedroom. My spare bedroom is a reserved area for my own animals when they need their own space. Aside from that room there is not a single limit for your pup! Cats I typically do not allow in my personal bedroom. This is so that my own can rest in there to prevent any issues overnight. No dangerous items or household supplies are ever left out, all toys/bowls/beds/blankets are sanitized after boarding, and I have tons of treats and spare food on standby! All foods and treats are stored in a secure location and are packaged individually. This is to ensure no contamination in case of food allergies or sensitivities. I do have a large dog crate and a small crate if ever needed. I heavily prefer to keep animals free roaming any time I am nearby. However, puppies and younger dogs I typically will crate if I do have to leave (assuming they are used to a crate). Dogs that are non-crate trained I will usually sat up a gate or playpen style divider in one section of the home for additional security. My own animals during this time will be in an isolated space for safety as well.
