Grass Guard Max Chewable Supplement
Verified Jun 17, 2026
This is a chewable supplement for dogs designed to support digestion and help reduce lawn burn from urine. It uses chicken liver for palatability, dl-methionine to help modify urine characteristics, and includes probiotics, digestive enzymes, and plant ingredients like barley grass and yucca. It’s intended as a daily add-on to a complete diet rather than a standalone food.
Nutritionally, this is a targeted digestive and lawn-burn support supplement rather than a complete dog food. It combines dl-methionine, fiber sources, and plant ingredients with several probiotic strains and digestive enzyme fermentation products to support the gut while aiming to lessen grass damage from urine. It’s generally suitable for most adult dogs as long as it’s used alongside a balanced diet and under guidance if your dog has any urinary or kidney issues.

At a Glance
KibbleLab Review
Strengths
- Includes multiple probiotic strains (Lactobacillus acidophilus, Bifidobacterium bifidum, Streptococcus thermophilus) and fermentation extracts that can support a healthy gut microbiome and digestion.
- Contains dl-methionine, which is commonly used in lawn-burn products to help adjust urine characteristics, along with barley grass, yucca, and tomato pomace as additional fiber and phytonutrient sources.
- Chicken liver as a primary ingredient helps with palatability and adds some natural nutrients, making it easier to give to many dogs.
- Simple, tablet-style supplement with weight-based dosing, designed to be used in addition to a regular complete diet.
Considerations
- This is not a complete and balanced diet, so it should only be used as a supplement alongside a regular dog food that meets nutritional requirements.
- Contains chicken liver and dried skimmed milk, which may be problematic for dogs with chicken or dairy allergies or sensitivities.
- Dl-methionine alters urine characteristics; dogs with a history of urinary stones, kidney disease, or other urinary issues should only use products like this under veterinary guidance.
- Added sugars (maltose, glucose) are present to improve taste and texture; while small amounts are generally safe, they are not nutritionally necessary and may not be ideal for dogs needing very strict calorie or carbohydrate control.

Top 5 Ingredients Explained
01
Chicken Liver
Chicken liver is a nutrient-dense organ meat commonly used in pet foods and treats as a highly palatable protein source and flavor enhancer, providing concentrated vitamins (especially vitamin A and B-complex), iron, and copper that support energy metabolism, red blood cell formation, and skin/coat health in both dogs and cats. Because it is so rich, liver should be fed in moderation—excessive intake can cause vitamin A toxicity, and its high fat content and risk of bacterial contamination mean it should be properly sourced or cooked and limited for pets with pancreatitis or specific dietary restrictions.
02
Maltose
Maltose is a disaccharide sugar (two glucose molecules) commonly used in pet foods and treats as a carbohydrate source and sweetener to improve palatability and assist browning or texture in processed products. It provides quick energy but little nutritive value beyond calories, can raise blood glucose and contribute to dental issues, and may originate from malted grains—so it should be used cautiously in diabetic, overweight, or grain‑sensitive pets.
03
Glucose
Glucose is a simple, highly digestible sugar used in pet foods as a quick energy source, sweetener, humectant or processing aid, contributing readily available carbohydrates and calories. While dogs and cats can metabolize glucose for energy, excessive added glucose can promote weight gain, dental issues and worsen blood‑glucose control in diabetic animals (and cats do not perceive sweetness), so formulations for overweight or diabetic pets typically minimize added sugars.
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
Maltodextrin
Maltodextrin is a processed, rapidly digestible carbohydrate commonly used in pet foods and treats as a binder, bulking agent, texture improver and flavor carrier. It supplies easily metabolized calories but offers little in the way of vitamins, minerals or fiber, so excessive inclusion can contribute to weight gain or blood sugar spikes in obese or diabetic dogs and cats, and it may cause digestive upset in sensitive pets; sources can include corn, wheat, potato or rice, so check for potential allergen concerns.
