Briantos Adult Mini Lamb & Rice - dog dry food

They don't like the duck one at all and it doesn't agree with them. Every time I give it to them, it gives them diarrhoea. I'll throw it in the bin because it's costing me a lot, with buying probiotics, gastrointestinal food, etc. The lamb one works well for them; I bought these varieties to try and it's been a disaster.
