Sorry, previous post submitted before I'd actually replied, still getting the hang of the software here.
That's particularly highlighted where there are two people in a household - the dog is able to get 2 walks, and some large dogs really need that for health & welfare. But the same dog can only get 1 walk if there only happens to be one person living with him/her. Iniquitous really.
And it absolutely infuriates me that taking your dog (or cat, or other pet) to the vet for urgent treatment isn't one of the essential reasons given. Had to take my dog in twice last week as he was very poorly, to his vet 10 miles away. The second time he had to stay in for the day on a drip, then I had to collect him in the evening. The police would apparently have had the discretion to make me turn back if they'd stopped me at a roadblock, and/or fine me. Ridiculous. These requirements need to be put on the statute book, and all possible exceptions which are reasonable, set down. Meanwhile, whether your dog lives or dies is apparently something an individual police officer has the power to decide - I hope this is unlikely, but I'm pushing the example to make my point clear.
