This dog needs insurance that is for sure, and the cover needs to start today preferably before our next walk Anyone with any advice?
You are unlikely to find a policy that starts straight away for illness; and some have an introductory period for ALL claims, injury as well as illness.
In view of his issues, I would recommend a more specialist company like PetPlan; you might pay more for the policy, but imo, they are more likely to offer you comprehensive cover; some of the cheaper companies will include blanket exclusions (for any ear treatment, for instance), whereas PetPlan seem to be more specific with the the exclusions they specify
