Havanese dental diet for periodontitis

Early periodontitis in a 10-year-old Havanese is very common — small breeds pack a lot of teeth into tiny jaws, which means tartar builds faster and gum disease can quietly take hold before owners notice any pain. The good news is that catching it early gives you real options. Your vet's advice to add a dental diet food alongside your brushing and care routine is solid — these foods are clinically designed to mechanically scrub teeth as the dog chews, reducing plaque and slowing progression. Before I point you to a specific product, can I ask: is your Havanese currently on any particular dry food, and is the periodontitis affecting the front teeth, back teeth, or spread across the mouth? That helps me make sure the kibble size and texture will actually work for her.

That makes complete sense — you don't need to overhaul her diet, just introduce something that does meaningful dental work at mealtime. For back molar tartar in a small older dog, the kibble needs to be large enough that she actually chews it rather than swallows it whole, but not so large it's hard on her jaw. Can I ask one more thing: does she have any known sensitivities or allergies, or is she otherwise eating well with no digestive issues?

Perfect — then my recommendation is Hill's Prescription Diet Dental Care t/d Small Bites. This is the gold standard vet-recommended dental diet, and it holds the VOHC (Veterinary Oral Health Council) seal, which means it has independent evidence behind the claim. The kibble is specifically engineered with a fibrous matrix that doesn't shatter when bitten — instead it wraps around the tooth and scrubs down toward the gumline as the dog chews. The small bites version is sized for dogs under about 13kg, so it's right for a Havanese. Because it's a prescription diet you'll need your vet's sign-off, which given they've already flagged the periodontitis should be straightforward — many will authorise it at the same appointment. You can use it as a meal replacement or as a significant portion of her daily food. It won't replace brushing, but combined with what you're already doing it will meaningfully slow tartar accumulation on those back molars.

Hill's t/d works best when it makes up the majority of her daily intake — ideally at least 75% of her dry food calories — because the mechanical scrubbing only happens when she chews that specific kibble. If you dilute it too much with her regular food, you lose most of the benefit. The practical approach most owners take is to transition it in over a week or two, gradually replacing her existing food, and use her current kibble as a small topper if she needs the palatability nudge at first. At 10, her calorie needs are fairly stable, so as long as you keep total portion size consistent she should be fine. One thing worth mentioning: t/d is nutritionally complete, so once she's fully transitioned she doesn't need the old food at all — but given your vet already has her on a care plan, just loop them in on the switch.

That's exactly the right move. Given they've already raised the periodontitis, they'll almost certainly be pleased you're being proactive about it. Early-stage gum disease in small dogs can be held stable for years with consistent home care and the right diet — it doesn't have to progress. Good luck with her next check, and if you have questions once you've started the transition, feel free to come back.
