three years with our frenchie and the heat thing finally caught up with us last june, writing down the summer protocol we built with our vet in case it helps another brachy family

Marbles is a 3 year old french bulldog, BOAS corrected at 18 months (stenotic nares plus elongated soft palate), generally a healthy frenchie by frenchie standards. Last june we took her on what we thought was a normal morning walk, 73 degrees, mostly shade, and she had a near miss. She started open mouth breathing within 4 minutes, then her tongue went a color i had never seen, then she sat down and refused to move. We carried her home and i sat with her on the kitchen tile for 40 minutes pouring room temperature water on her belly and groin while my partner called the emergency vet. She was fine within 90 minutes. The emergency vet said we caught it in time. I would call us extremely lucky.

That night we did a real sit down with our regular vet and built a summer protocol. I am writing it out because almost everything i had read online before that day was either "dont walk your frenchie in summer" (not actionable, we live somewhere with 5 months of warm weather) or "they are tougher than people think" (factually wrong for a brachy dog). Neither helped us. The protocol our vet gave us is specific and i want to share it for anyone with a brachy who is trying to actually live their life with the dog instead of just gatekeeping themselves from leaving the house.

The protocol. We dont walk Marbles when the temperature plus humidity hits 150 on the dew point chart. Practically that means anything above 75 degrees with humidity above 60% she stays home, and above 80 degrees full stop. We walk before 7am and after 8pm, on grass not pavement (pavement adds 20-40 degrees to the surface temp under her belly). She wears a cooling vest soaked in room temperature water (not cold, cold actually constricts surface vessels and slows cooling) for any walk above 70 degrees. We carry 16 oz of room temp water and a small spray bottle on every walk. We watch for the first sign of any change in breathing pattern not the third sign, which means if her breathing gets faster or louder at all we sit down in shade for 5 minutes minimum. We never let her run or play hard outdoors in summer, hard play happens indoors in AC. Yard time in the afternoon is limited to 8 minute supervised sessions with shade and water and we go in if she seeks shade unprompted.

What we changed at home. We added a second AC unit in our bedroom so she has somewhere consistently cool to retreat to. We bought a cooling mat (the gel kind, she actually uses it now after 2 weeks of ignoring it). We put a kiddie pool in the back yard but she only uses it about half the time, you cant make a frenchie love water. We started feeding dinner in slow feeders to slow down the post meal heat spike (frenchies generate a lot of internal heat digesting). We learned the signs of early heat stress in writing on the fridge, open mouth breathing at rest, tongue going purple-red not pink, gum color change, refusal to walk, dazed eyes. If we see any of those things, room temp water on belly groin armpits, fan, get to a vet.

What i wish someone had told me before last june. The temperature reading on your phone is not the temperature on the pavement where your dog is. Brachy dogs cool by panting and they cannot pant efficiently, which is the entire problem. BOAS surgery helps but it does not make your frenchie a normal dog in summer. The "she seems fine" feeling is not data, by the time you can see they are not fine they are already in trouble. Cool water not cold water. Belly and groin and armpits not the head and back. Call the vet sooner than you think you need to.

We had a near miss and got lucky. Posting in case someone else's near miss is still ahead of them and this saves them five minutes when it counts
