Actually, bonding is different from being insured. I believe that bonding covers employees who may come into your home and steal from you. What you are looking for is an in home petsitter (I assume where Ellie would stay with the sitter at their home) to have insurance. Since we watch dogs in our home, I have insurance like that. I am insured if something happens to a dog in my care. I do not have any bonding since I do not go into anyone's home or have any employees who do that. I hope that makes sense.
After working for a bank and being taken, at gun point, during a robbery, by one of the BONDED cleaning service people, I take bonding with a grain of salt. It may prevent a small amount of petty theft. Real thieves know how to get false ID's and credentials (the robber who took me had 6 sets in his home when he was arrested) that make it a snap to get bonded.
If I had to leave Kodi with someone I didn't know well, I'd want to check it out carefully in person, and I'd also want references, not only from clients, but from other dog professionals, like trainers, groomers and vets. That would mean more to me than whether they were bonded.
As far as insurance is concerned, insurance might be nice, but if something happens to my dog, nothing is going to bring him back. Again, I'd rather have a real feeling that the care provider will take just as good care of him as I do. Things happen, and dogs do hurt themselves. I want to feel that if something DID happen to Kodi while in their care, it would be one of those things that could happen anytime, anywhere, even with me.
