I think it is paramount to point out here it is the public liability bit that is the problem.
Injury to the dog they won't ask you where you were or what dog was doing when it got hurt. I have claimed twice for my dogs for injuries on a shout and neither have asked what dog was doing at time.
The problem is what happens if an outside party is involved for example dog knocks someone over
, causes a crash, damages something belonging to someone etc etc. This is the area they all seem to shut of to offering when you mention that the dog is a working dog being a search dog even though no payment is received.
All four of mine are insured with Pet Plan. All of them have added bit that covers them for search yet pet plan if you ring them say they don't do it. I think maybe I got in before they realised and so now they have carried it on fir me. I check very carefully each renewal time!
I know others have insurance that does cover the dog whilst working so we should be able to let members know who it is worth going to.
