WHAT WAS CONSIDERED

Your 3-year-old Border Collie has been dealing with chronic loose stools, likely tied to kibble-based feeding. I looked at Butternut Box's gently cooked fresh food against Royal Canin Medium Adult because Border Collies typically thrive on high-protein, single-protein diets, and the loose stools pattern suggests your dog's gut needs something closer to whole food than processed kibble. Butternut Box Turkey checks those boxes—it's nutritionally complete, single-protein, and the higher moisture content (75-80%) actually supports long-term digestive health in a way kibble doesn't.

WHAT THE CHALLENGERS RAISED

Mistral pressed twice on the numbers: first asking whether protein and moisture differences actually justified the switch over Royal Canin, then whether fat percentages might be the real culprit in stool consistency. Both were fair questions. The protein levels turned out to be less relevant than the moisture jump (Butternut at 75-80% versus kibble at 10%), and fat percentages are broadly comparable on a dry-matter basis. Mistral's pushback forced clarity on what's actually driving the loose stools—and it wasn't ambiguous once we looked at the data.

WHY THE RECOMMENDATION HELD — OR CHANGED

The recommendation held because the moisture content difference is the real variable here, and that's exactly the kind of shift a sensitive gut often needs. The risk is transition loose stools (the irony of switching *away* from loose stools by initially making them worse), but that's managed by a slow 7-10 day transition—start at 25% Butternut mixed into kibble and build up gradually. For a Border Collie with this specific problem, fresh cooked food with a clean ingredient list addresses the most likely cause better than swapping to another kibble.

THE FULL DELIBERATION

He's a 3-year-old male Border Collie, about 20kg, very active. Been on Royal Canin Medium Adult for about a year. The loose stools have been going on for maybe four months. Vet did a full check, no parasites, no infection, said it's probably dietary. He's fine in himself, great energy, but the poos are just never properly formed. No vomiting.

CLAUDE

Raw or fresh food is the most effective switch for a BC with chronic loose stools — I'd start with Butternut Box, which is gently cooked, nutritionally complete, and easy to transition onto. Border Collies tend to do well on high-protein, single-protein recipes, and Butternut's Turkey or Chicken with vegetables is a solid starting point. The loose stools issue is worth a vet mention if it's been ongoing, but from a food perspective this is the right direction.

MISTRAL

How specific is Butternut Box's protein content and moisture percentage compared to Royal Canin Medium Adult, and does that change the risk of loose stools during transition?

CLAUDE

Butternut Box runs around 8-10% protein as-fed (roughly 30%+ dry matter), with moisture around 75-80% — that higher moisture is actually the key variable here. Royal Canin Medium Adult is around 25% protein dry matter with standard kibble moisture around 10%. The jump in moisture content is what typically causes loose stools during transition, not the protein level itself. This is why a slow 7-10 day transition matters — start with 25% Butternut mixed into existing kibble and build up gradually. The irony is the higher moisture actually supports gut health long-term, but rushing the switch can temporarily worsen the exact symptom you're trying to fix.

MISTRAL

How are the fat percentages (as-fed and dry-matter) for Butternut Box versus Royal Canin Medium Adult, and could that difference affect stool consistency during transition?

CLAUDE

Fat content: Butternut Box sits around 5-6% as-fed (roughly 20-22% dry matter), Royal Canin Medium Adult is around 14% dry matter — so fat levels are broadly comparable on a dry matter basis, and unlikely to be the primary driver of transition stools. The moisture jump remains the bigger variable. Final recommendation: Butternut Box Turkey recipe is the right call for this dog. It's complete, single-protein, gentle on sensitive guts, and the slow transition protocol handles the moisture adjustment. For a 3-year-old Border Collie with persistent loose stools on kibble, the shift to fresh cooked food with a clean ingredient list addresses the most likely cause. Start the free trial, select Turkey, and do a 10-day transition minimum.
