Well done you for remaining calm, your blood must have been boiling!!
I am so glad you were able to get your point over too, if you had had a shouting match, she wouldn't have had the benefit of your experience (even though you may think it is limited!).
Hopefully she will be a bit more relaxed.
I managed a rescue for a large charity, with responsibility for 40 dogs adn 30 cats, with a few smaller animals. Everyone who adopted a pet underwent a indepth uesionaire, a home visit and had to attend an evening lecture (if they were taking on a puppy), The dogs we had being rehomed often had other problems and we were always there to give advice, ideally what to expect when they got the dog. Whlst some are like this, there are others who are not.
When we got our last dog a stray I found who subseuently got taken to the rescue, where we went and adopted her, they didn't ask anything, not if we had other dogs, worked, a garden, house, flat or children. All they wanted was the money - I was gobsmacked at their attitude, they also re-homed the dog in the same area that it was found - not good practice.
Unfortunately there are not standards for rescue centres, only the kennel facilities, anyone can run a rescue and anyone can own a dog - scary world really!
