I totally get that, since on my second sit, it was assumed the dogs would go in my car. And drive them everyday to the dog run, no gas money. Now, I say my car has too much stuff in it.
I have a similar issue- the HO has made their car available so that I can take their dogs on longer walks. There are a few medium walks just out the door. I am also able to use the car for personal use. We have struggled to find a way to insure me- with a Californian driver’s license in the UK. In the end it’s quite expensive. Any-one have similar experience, and how did you handle it?
