I don’t know if you ever hired a pet sitter for your animals, but you should considerate. Most pets love having someone in their homes to care for their needs. The pet sitter stays as a family member to make sure the pet has water and food. Dogs like to run in packs so the pet sitter while staying overnight helps the pet adjust to being without his family.
I recommend all animal lovers have someone stay with their pets because its healthier and safe. Pets are happy in their own environments because they are comfortable.
