Hello, this is Dr. Bruce and I would like to help you with Hudson.
I'm sorry to hear that he is having this issue.
Has your vet run any bloodwork to check for internal organ issues? Has a fructosamine test been run (checks to see if the diabetes has been under control for the prior 3-4 weeks)? Any x-rays?
I would suggest running the above mentioned tests to look for any specific problems.
Having said that, I would consider putting Hudson on a bland diet such as Hill's i/d or Purina EN for easy digestion. A trial course of a gastroprotectant such as famotidine may be helpful.
It is possible that Hudson merely has gastric reflux that comes with old age. In that case, giving him a small meal right before bedtime so that his stomach is not empty when he sleeps would be very helpful. A dose of famotidine at bedtime will also help. By doing this, his stomach will be protected and he will not wake up with "sour stomach".
I hope this helps and that Hudson is feeling better very soon. If you would like to continue this chat, please reply to this post and I will get back to you as soon as possible.
Hi, thank you so much for your help and advice, since last week when I received your reply, I have started to give Hudson, a small amount of 'kibbles'. at .about 10pm each night, so far, touch wood, this seems to be working
