Hi watermeadow, so sorry to hear how let down you have been by your daughters. I volunteer for a charity that rehouse a specific breed of dog. Volunteers would also help out by dog walking for someone in your circumstances. I don't live anywhere near you, otherwise I'd be happy to dog walk for you. The Cinammon Trust sounds a good idea, as recommended by someone up thread. I understand why kennels is being recommended but I know in your position, I'd want the company my dogs would give me, providing I could get help in looking after them.
I hope the op goes ok,that your recovery is straightforward. I absolutely agree with those who say that if you've any money to spare, buy in some care for your dogs. There are so many professional dog walking/house sitting services available now. Any spare cash, get it spent on making your life as comfortable as you can - spend any inheritance you'd been saving (apologies if there is no spare cash x)
