GrassSaver Soft Chews Supplement
Verified Jun 5, 2026
This is a soft chew supplement for dogs designed to be given alongside their regular diet to support urinary tract health and help lessen urine-related lawn spotting. It uses dl-methionine, cranberry fiber, and yucca, along with a vitamin B blend and probiotics, to influence urine characteristics and support urinary and kidney function. It’s intended for dogs over 12 weeks old and is not suitable for cats.
This is a targeted supplement rather than a complete diet, aimed at dogs who have issues with yellow spots on the lawn and owners who also want some urinary tract support. The active ingredients are commonly used in veterinary products for urine pH modulation and urinary support, and the inclusion of probiotics and digestive enzymes is a nice bonus. As with any methionine-containing product, it’s best used as directed and ideally with guidance from your veterinarian, especially for dogs with any history of urinary or kidney problems.

At a Glance
KibbleLab Review
Strengths
- Contains dl-methionine, cranberry fiber, and yucca, which are commonly used ingredients in products designed to support urinary tract health and help reduce lawn burn from urine.
- Includes a vitamin B blend, probiotics (Bacillus coagulans), and digestive enzymes that can support overall digestive health while the main actives address urine-related concerns.
- Soft chew format is generally easy to give, especially for dogs who resist tablets or powders.
- Formulated specifically for dogs and labeled for use starting at 12 weeks of age, which offers clear age guidance for owners.
Considerations
- This is a supplement, not a complete and balanced food, so it should only be given in addition to a regular, nutritionally complete diet.
- dl-Methionine alters urine characteristics; in dogs with a history of urinary stones, kidney disease, or other urinary issues, it’s important to check with your veterinarian before using it long term.
- Contains brewer’s dried yeast and potato, which are fine for most dogs but could be an issue for a dog with a known yeast- or potato-specific sensitivity.
- Multiple added ingredients (flavorings, starches, oils) increase palatability and texture but also add extra calories, which may need to be considered in smaller or weight-prone dogs if used daily.

Top 5 Ingredients Explained
01
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.
02
Cranberry Fiber
Cranberry fiber is a fiber-rich ingredient derived from cranberry pomace used in pet foods to provide soluble and insoluble fiber for digestive health and improved stool quality, while also contributing antioxidant polyphenols. In dogs and cats it can help regulate intestinal transit and fecal bulk and may supply cranberry compounds sometimes associated with urinary tract support, but evidence is limited and high inclusion levels can reduce calorie density, affect palatability, or cause loose stools, so it should not replace veterinary treatment when needed.
03
Vitamin B
Vitamin B refers to the B‑complex group of water‑soluble vitamins commonly added to pet foods to support energy metabolism, nervous system function, healthy skin and coat, red blood cell formation and appetite, and are often supplemented because processing and storage can deplete natural levels. These vitamins are essential for both dogs and cats (cats have a higher thiamine requirement and may show neurologic signs if deficient); they are generally safe because excess is excreted in urine, but true deficiencies require veterinary diagnosis and targeted supplementation.
04
Biotin
Biotin (vitamin B7) is a water‑soluble vitamin added to pet foods as a micronutrient to support energy metabolism and healthy skin, coat, and paw pad integrity in dogs and cats. Deficiencies are uncommon with commercial diets but supplementation can help with dermatitis or poor coat quality—biotin is generally safe at recommended levels, though therapeutic or high‑dose use should be done under veterinary guidance and raw egg whites can interfere with biotin absorption.
05
Vitamin B12
Vitamin B12 (cobalamin) is an essential water‑soluble vitamin commonly added to pet foods and supplements to support red blood cell production, neurological function, DNA synthesis, and normal energy metabolism in dogs and cats. It helps prevent deficiency signs such as anemia, poor appetite, weight loss and neurologic abnormalities, and is particularly important in diets low in animal ingredients or in pets with gastrointestinal malabsorption—generally safe because excess is excreted, though animals with GI disease may need higher or parenteral dosing under veterinary guidance.
