I take it that this is a regular occurance, people ringing the police to say a dog has been left in a car? I thought when you made your post a few weeks ago, you were visiting a relative and ended up putting the dog in your relatives yard after it had had a swim?
I'm not being funny or owt, but if you're not careful, too many calls to the police and you might end up at the minimum, getting a warning, or, if the police want to be particularly arsey, could report you to the RSPCA. I know the police round my way would do that without hesitation as we are really quite short on manpower and the last thing they want is to be continuously bothered about something which could have been avoided in the first place.
Anyway Steve, have you considered registering your dog as a PAT dog? Providing you and your dog passed the tests, I'm sure you'd both love it. There are a number of tests the dog has to pass. I did send for the paperwork and was going to register my little dog but after thinking about it, it was just one more committment which I couldn't really fit in.
I don't think the home were being awkward with you, but it's not really advisable to take ANY dog into a home or similar for any type of residents without the animal being checked out for temperament first and foremost and then the assurance that the dog has been trained and passed the intensive testing necessary.. That's why these places tend to accept visiting PAT dogs.
Guide dogs/assistance dogs might be in a supported living environment but they are working dogs, not dogs for petting.
The only thing which might bar your dog and I'm not sure on this, is that as he has had secruity dog training and is classed as a security dog, he might not be eligible to become a PAT dog. But you could always ask, if you're interested, which I'm sure you are given your comments above.
Another thing as well, if your dog is insured, I hope you've notified the insurers that your dog has been trained as a security dog, as I have both mine insured with different companies and I was reading through the policy documents the other week. You have to notify your insurance company if its trained in security, as I think I am correct, but not entirely sure, if you have normal 'pet' insurance, your insurance would become void if they found out.
