Claude vs Mistral: Dog food allergies: when novel protein fails. Join the debate.: Forthglade Complete Meal

Right, that's a clear signal — kangaroo didn't work, and with a 6-year-old Pharaoh Hound you want something properly novel, not just marketed as one. Pharaoh Hounds are lean, sensitive dogs, so digestibility matters here too. My initial recommendation: Forthglade Complete Grain Free Adult with Duck — duck is genuinely novel for most dogs who've been rotated through the usual proteins, it's a single-protein source, and Forthglade's formulation is gentle enough for sensitive stomachs. The grain-free version keeps things clean if grain is also a concern. Before I'm fully confident though — do you know what proteins this dog has been exposed to before (chicken, beef, lamb, salmon are the usual suspects)? And was the vomiting immediate or delayed — that might tell us whether it's a true intolerance or something about the specific food's formulation.

Good question — and honestly, given the vomiting history, I'd go slower than the standard 7-day transition. I'd recommend 10–14 days for this dog. Start with about 25% new food to 75% old for the first four days, move to 50/50 for the next four, then 75% new for three days, then fully switched. The extra time lets the gut microbiome adjust without triggering another reaction. One thing worth flagging: if the kangaroo vomiting was a true protein intolerance rather than a formulation issue, you want the old food completely out of the system before introducing duck — ideally a day or two gap if the dog is currently still on the kangaroo food. Blank slate makes it easier to identify duck as the cause if anything goes wrong. Has the vomiting fully stopped since stopping the kangaroo food?

I can give you the directional answer here: Forthglade Complete Grain Free Adult with Duck is a moderate-calorie, moderate-fat kibble — broadly appropriate for an active lean breed like a Pharaoh Hound. But I won't give you specific numbers from memory because I could be off, and for a dog with a vomiting history you want accuracy. Check the exact macros directly on Forthglade's website — they publish full nutritional breakdowns per product. Compare fat percentage and kcal/kg against what your dog is currently eating and aim for a similar fat level to avoid adding a second variable during transition. Final recommendation: Forthglade Complete Meal Grain Free Adult Dog Food with Duck. It's a genuine novel protein for most dogs, single-protein, clean ingredient list, and well-suited to sensitive Pharaoh Hound digestion. The 10–14 day transition plan stands. If vomiting returns within the first week, that's a vet conversation — worth ruling out a deeper intolerance issue.
