Hi
Background
we've got two dogs, one lab 4.5 years, one mixed bag 17 years. The lab who I've had since 8 weeks has a recurrent stomach upset every few weeks. It essentially shows itself by him going off food initially, followed by horrible sounding gut noises (we call it gurgle guts!) followed by lots of grass eating and sickness (which is why I am up and awake here at 4am!).
It used to be once a month or so but over the last few months it seems to have become more frequent. Only real reasons beyond normal I can think of are that it is winter and therefore get more excerise walking pavements rather than charging round fields (more likelhood of picking up other dogs bugs?) and that I'm 33 weeks pregnant with 1st (and he's reacting to this in some way).
I know labs will tend to eat anything and everything but he's always been a bit fussy about food. Doesn;t like certain brands of dog food and could happily leave a big bag of food and he wouldn't gorge himself (although the 17 year old would have a good go!).
We have spoken to the vet before who doesn't seem that bothered really. just says he has probably eaten something dodgy which labs tend to do, starve him for 24 hours and then chicken and rice for day or so. Basically says that as long as drinking water and doesn't seem in pain then just deal with it amd that is what labs do!. We have also changed food into something more bland (Pets at home own brand food which was suggested) which although he seems to prefer, problem is still there. That's fine, but it does seem to be a regular recurrent problem and I just get the feeling that it shouldn't be this way and something is wrong - not least it keeps making him a bit miserable every few weeks. I am tempted to take him back to vets and push the issue.
Sorry for rambling in the small wee hours but grateful for any advice!
