The Vet-Recommended Dental Treat Small Dogs Actually Get Excited About

The entire point of a Greenie is mechanical cleaning. The chewy, bendable texture forces your dog to chew rather than crunch-and-swallow, and the toothbrush-inspired shape with ridges and nubs lets teeth sink in toward the gumline. That chewing action scrapes away soft plaque and food debris before it hardens into tartar — something a plain biscuit simply cannot do.

Greenies also carry the VOHC Seal of Acceptance, awarded by the Veterinary Oral Health Council. The VOHC does not test products itself; it reviews clinical data submitted by manufacturers and awards the seal only to products that demonstrate real plaque and/or tartar reduction. Greenies Original earned the seal in 2007 and has maintained it since. According to data on file from the manufacturer, daily use supports 47% less tartar accumulation and 40% less plaque accumulation over 28 days.

Sizing is the single most important decision with any dental chew, and it is the root of most safety complaints. The Teenie size is calibrated for dogs 5–15 lbs, which covers many of the breeds at highest risk for periodontal disease — Chihuahuas, Toy Poodles, Yorkshire Terriers, Shih Tzus, Maltese, and Pomeranians. Research from Banfield/Waltham published in The Veterinary Journal confirms small breeds face two to three times the periodontal disease risk of larger breeds.

If your dog is between sizes or tends to gulp treats, round down to the smaller size. A chew that is too small for a large dog is a choking hazard, and a chew that is too large for a small dog can overwhelm their mouth. Greenies also makes Petite (15–25 lbs), Regular (25–50 lbs), Large (50–100 lbs), and Jumbo (100+ lbs) sizes if your dog outgrows the Teenie range.

If you have researched Greenies, you have likely come across stories about choking or intestinal blockages. These concerns are real and worth understanding. Between 2003 and 2006, CNN and other outlets reported cases where dogs — particularly small breeds and aggressive gulpers — experienced esophageal or intestinal obstructions from the original Greenies formula. A board-certified veterinary internist, Dr. Brendan McKiernan, published research showing compressed vegetable chews were the third most common cause of esophageal obstruction in dogs behind bones and fish hooks.

In response, Greenies reformulated the product in 2006 to be far more soluble. The current chew breaks down much faster in the digestive tract, even if a piece is swallowed without thorough chewing. The packaging also added clear weight-based sizing guides and a reminder to monitor your dog while they chew. The FDA reviewed the complaints but did not order a recall.

That said, no chew is completely risk-free. Dogs that gulp treats whole, flat-faced breeds, and dogs with dental issues need extra supervision. Always match the size to your dog's weight, watch them chew, and keep fresh water available.

The Greenies Original base is wheat flour and wheat gluten, bound with glycerin for chewiness and flavored with natural poultry. It is fortified with vitamins (E, B12, B5, B2, B1, B6, A, D3, biotin, folic acid) and minerals (zinc, iron, copper, manganese, magnesium, selenium, iodine). The chew is rawhide-free, bendable, and will not snap.

The wheat base is the main thing to watch. If your dog has a grain or wheat sensitivity, skip the Original and look at the Greenies Grain-Free formula instead, which swaps wheat for potato. The guaranteed analysis shows 28% minimum crude protein, 5.5–8% crude fat, 6% max crude fiber, and 15% max moisture.

Think of Greenies as the easy daily layer of a three-part dental plan. Brushing is still the gold standard — a toothbrush physically removes plaque from every tooth surface, including the inner faces a chew never touches. Professional cleanings sit at the top of the ladder, because only your vet can scale hardened tartar below the gumline.

Greenies work best as a daily backup to regular brushing. Used consistently, they slow plaque and tartar buildup between vet visits. Relying on chews alone, with no brushing or professional care, is where disappointed owners tend to go wrong. Greenies reduce buildup between cleanings — they do not reach below the gumline and do not replace a professional dental cleaning.
