We have a thread on dogs with a sensitive digestion system here.
There might be something of use in it. The symptoms seem to point to intolerance or maybe could be due to the dog’s immune system.
Dry food is probably not going to be the best thing for your dog because they tend to be high in carbohydrate and this is reputed to stimulate yeast growth in susceptible dogs. You could try a high protein one e.g. 80/20 but they sometimes have complex, multi meat formulas and with a dog like yours it is best to keep it simple. I don’t know whether these will suit your dog - we hear that some dogs have loose stools when on such foods but in fairness that could be due to overfeeding.
Some things to consider:
* See your vet and start a proper, tightly controlled
elimination diet. They often start with a prescription food containing hydrolysed protein source. Different foods are then added very gradually and the dog’s response monitored. Takes a while but can be useful.
* Consider a home cooked diet but research this thoroughly first.
* I appreciate you dislike feeding raw but it is something to consider because of the low carb. If you go for raw complete it is no different to feeding tinned food. You don’t have to handle it. If you are minded to try this again, please choose one of the larger companies and ask for their help/advice because you need to give one food at a time to monitor the dog’s response.
* Low carb wet food e.g. Natures Menu Country Hunter, Forthglade. There are more and they can be found using the Dog Food Directory. Again, one flavour at a time to monitor response. These can be expensive though.
