GrassSaver Biscuits Supplement
Verified Jun 20, 2026
A crunchy peanut butter-flavored biscuit supplement for dogs designed to be given alongside a regular diet. It uses dl-methionine, yucca, and psyllium husk with a brown rice and chicken meal base to help modify urine characteristics while providing a modest amount of protein and fat. This product is meant as a lawn-protection supplement, not as a complete and balanced dog food.
This is a lawn-focused supplement biscuit, not a complete diet, and it’s formulated to be given in small amounts with your dog’s regular food. The protein and fat levels are appropriate for a biscuit, and the main ingredients (brown rice, chicken meal, barley, peanut butter, and flaxseed) are standard, palatable choices. Its relatively high dl-methionine content means it should be used exactly as directed and only for dogs, not cats, and is best suited for otherwise healthy dogs with no known urinary or kidney issues, under veterinary guidance if there are any concerns.

At a Glance
KibbleLab Review
Strengths
- Uses familiar, digestible carbohydrate and protein sources like ground brown rice, chicken meal, and barley that most dogs tolerate well.
- Includes psyllium husk and flaxseed meal, which can support normal stool quality and provide some fiber and omega-3 fatty acids.
- Clearly designed and labeled as a supplement to be fed in limited quantities alongside a regular, complete diet, which helps prevent it from displacing balanced nutrition.
- Calorie content per biscuit is provided, which makes it easier to factor these into your dog’s overall daily calorie intake to avoid weight gain.
Considerations
- Contains chicken and peanut butter, which can be problem ingredients for dogs with chicken or peanut allergies or sensitivities.
- Formulated for intermittent or supplemental feeding only, so it must not replace a complete and balanced dog food.
- Relies on a relatively high level of dl-methionine to influence urine characteristics; in dogs with existing kidney, liver, or urinary issues, it’s wise to talk with your veterinarian before using it.
- Not safe for cats, and should be kept out of reach of multi-pet households where a cat might access the biscuits.

Top 5 Ingredients Explained
01
Brown Rice
Brown rice is a whole-grain carbohydrate and fiber ingredient commonly used in dog and cat foods to provide digestible energy, dietary fiber, and modest amounts of B‑vitamins and minerals; it typically offers more nutrients and fiber than white rice. It’s generally well tolerated and can help with sensitive stomachs, but because it is high in carbohydrates (not a primary protein source) and can contain trace inorganic arsenic depending on sourcing, it should be included in balanced formulations and monitored in overweight or diabetic pets.
02
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
03
Barley
Barley is a cereal grain used in pet foods primarily as a digestible carbohydrate and source of dietary fiber (including soluble beta‑glucans), along with modest amounts of B vitamins and minerals. It can support healthy digestion, help moderate post‑meal blood sugar and aid weight management in dogs, but provides limited protein for obligate carnivores like cats, must be cooked/processed for good digestibility, and may be unsuitable for pets with grain sensitivities or calorie‑restricted diets.
04
DL-Methionine
DL‑methionine is a synthetic, racemic form of the essential sulfur‑containing amino acid commonly added to dog and cat foods to meet methionine requirements for protein synthesis, support skin and coat health, and to acidify urine when clinically indicated to help prevent struvite crystals. Only the L‑isomer is directly used by the body (the D‑isomer is converted), and while it can be a precursor to cysteine and indirectly to taurine, it does not replace dietary taurine for cats; excessive supplementation can upset amino acid balance or over‑acidify urine, so it should be used at recommended levels.
05
Psyllium Seed Husk
Psyllium seed husk is a soluble, fermentable fiber derived from the psyllium plant commonly added to pet foods and supplements to bulk and regulate stools, helping relieve constipation, normalize diarrhea, assist hairball passage in cats, and support colonic health. Because it swells when hydrated, it must be given with plenty of water to avoid esophageal or intestinal obstruction, can alter absorption of some oral medications, and should be introduced gradually and used under veterinary guidance rather than as a source of calories or protein.
