This might be long.
We have an almost 14 year old dog who has recently been diagnosed with Mitral Valve Disorder. He's on numerous medications to manage his symptoms and by all accounts remains a happy, healthy (bar the heart) dog for his age (as said by one of the best dog cardiologists in the country). One of the medications is a diuretic, which of course means an absolutely massive increase in water intake and the inevitable accidents in the house.
We both work full time out of the home and our dog is (and has been his whole life) left for 5 hours a day. We are in the process of arranging working from home days, so there is always somebody home with him moving forward and can take him out to the toilet much more frequently (we don't have a garden) however this will take a few weeks to get approvals and equipment ordered etc.
I'm looking for advice on ways to cope until then from someone who has experienced similar themselves. Every day we are coming home to floods of pee, all over his bed and it has already damaged the floor (which is fine, it's not his fault at all). Any waterproof bed recommendations for a senior dog? Any "puppy pad" type things (not sure a standard puppy pad would be sufficient for what we are dealing with)? Any other things that might help us manage this until we sort out the working from home situation?
He's a long haired breed so we are also going to start having his gorgeous coat trimmed very short so his fur isn't getting saturated too as he isn't enjoying the daily baths either.
Please, no put to sleep advice, he genuinely is still a happy dog, mostly runs around like a puppy, eats well, still loves walks and trying to fight the postman and, except for the urination has an excellent quality of life.
Thanks In advance.
