Dogs eating mulch is a common behavior and can be concerning for pet owners. There are several reasons why dogs are attracted to mulch, and fortunately, there are ways to address this behavior and prevent harm to your furry friend.
One reason dogs may eat mulch is out of curiosity. Dogs explore the world through their senses, and the smell and texture of mulch can be intriguing to them. Another reason could be boredom or anxiety. Dogs may resort to chewing on mulch as a way to alleviate stress or simply because they are lacking mental stimulation.
To stop dogs from eating mulch, it is crucial to address the underlying cause. First, ensure that your dog has plenty of mental and physical exercise. Engaging in regular playtime and providing interactive toys can help curb their destructive chewing behavior. Additionally, providing alternatives such as chew toys specifically designed for dogs can redirect their attention away from mulch.
It is also essential to make the mulch inaccessible. Create a barrier between the dog and the mulch by using fencing or covering the area with rocks or gravel. Alternatively, you can train your dog to avoid mulch by using positive reinforcement techniques. Teach them the “leave it” or “drop it” command and reward them with treats or praise when they obey.
In some cases, eating mulch can be a sign of a medical issue or nutritional deficiency, so it’s advisable to consult with a veterinarian if the behavior persists or if you notice any other concerning symptoms.
So understanding why dogs eat mulch is crucial in order to address the behavior effectively. By providing appropriate physical and mental stimulation, redirecting their attention, creating barriers, and training them using positive reinforcement, we can successfully deter dogs from eating mulch and ensure their safety.
Reasons Why Dogs Eat Mulch

Nutritional Deficiencies
One of the main reasons why dogs eat mulch is due to nutritional deficiencies. Dogs may turn to eating non-food items such as mulch to compensate for a lack of nutrients in their diet. The following are some common nutritional deficiencies that can cause dogs to eat mulch:
Inadequate Diet
If a dog is not receiving a well-balanced diet, they may start to crave other sources of nutrients. In some cases, this can lead to dogs eating mulch to satisfy their nutritional needs.
Mineral Imbalances
Minerals such as calcium and phosphorus are essential for a dog’s health. If a dog’s diet is deficient in these minerals, they may start to crave non-food items such as mulch.
Boredom and Lack of Stimulation
Another reason why dogs may eat mulch is boredom and a lack of mental and physical stimulation. Dogs that are left alone for extended periods without adequate exercise and playtime may become restless and start to find ways to entertain themselves, including chewing on non-food items such as mulch.
Insufficient Physical Activity
Dogs that do not receive enough exercise may start to develop destructive behaviors such as chewing on non-food items like mulch. Providing adequate physical activity can help to reduce this behavior.
Limited Mental Engagement
Dogs that do not receive enough mental stimulation may become bored and start to seek out other forms of entertainment, including chewing on non-food items such as mulch. Providing interactive toys and puzzles can help to reduce this behavior.
Pica: A Compulsive Eating Disorder
Pica is a compulsive eating disorder where a dog will eat non-food items such as mulch. Pica can be caused by several underlying medical conditions or behavioral issues.
Possible Causes
Pica can be caused by a variety of underlying issues, including:

Frequently Asked Questions
Let’s answer some of the most frequently asked questions about dogs eating mulch.
1. Is mulch digestible for dogs?
Mulch is not digestible for dogs and can be harmful if ingested in large amounts. Some varieties of mulch are made from materials such as cocoa bean shells, which can contain toxic substances like theobromine, the same compound found in chocolate and can be toxic to dogs. Ingesting large quantities of mulch may cause gastrointestinal upset, choking hazards, or even intestinal blockage. It is important to keep dogs away from mulch and provide them with safe alternatives for play and chewing. If your dog has ingested mulch or is showing any signs of illness, it’s best to consult a veterinarian for guidance.
2. What can you spray on mulch to keep dogs out?
One effective solution to deter dogs from entering mulched areas is to use a mixture of white vinegar and water. By mixing equal parts of vinegar and water in a spray bottle, you can create a natural and safe repellent to spray on the mulch. The strong scent of vinegar usually repels dogs as they do not like the strong odor. However, it’s important to note that this mixture may need to be reapplied periodically, especially after rain, as the scent can dissipate over time. Additionally, using physical barriers, such as fencing or rocks, can also effectively keep dogs out of mulched areas.
3. Is rubber mulch safe for dogs?
Rubber mulch has gained popularity as an alternative to traditional wood mulch in landscaping projects due to its durability and low maintenance. However, there is a concern regarding its safety for dogs. While rubber mulch is generally non-toxic and poses minimal harm if ingested in small amounts, there are a few aspects to consider. It may contain chemicals and heavy metals that could be harmful if large quantities are consumed. Additionally, the small rubber pieces can pose a choking hazard. Therefore, careful supervision and limiting a dog’s access to rubber mulch is advisable to ensure their safety and well-being.
4. How do I get my dog to stop eating tissues and dirty napkins off the street?
To prevent your dog from eating tissues and dirty napkins off the street, you can start by teaching them the “leave it” command. Begin indoors by placing a tissue on the floor and telling your dog to “leave it” while offering a treat. Practice this exercise gradually progressing to outdoor settings. Consistency and positive reinforcement are key. Additionally, ensure that your dog’s nutritional needs are met and they have plenty of engaging toys. Proper exercise and mental stimulation can help deter them from seeking out inappropriate items. Lastly, always keep a vigilant eye on your dog while walking and redirect their attention with their favorite toy or treat if they show interest in such items.
5. Why do dogs eat grass in the summertime?
Dogs eat grass in the summertime for various reasons. One possible explanation is that they use it as a natural remedy for digestive issues. Grass contains fiber, which can help dogs alleviate feelings of nausea or upset stomachs. Additionally, the increased availability of grass in the summer may make it more tempting for dogs to eat. Dogs might also eat grass out of boredom or to fulfill their natural urge to graze. While eating small amounts of grass generally isn’t harmful, it’s crucial to ensure that the grass has not been treated with chemicals or is toxic to dogs.
6. My dog ate mulch and is throwing up, what should I do?
If your dog ate mulch and is throwing up, it is important to monitor the situation closely. Mulch can be potentially harmful to dogs, especially if it contains toxic substances like cocoa mulch. Vomiting is a natural defense mechanism for dogs to expel something that may be causing irritation or poisoning. However, if the vomiting continues or is accompanied by other concerning symptoms such as lethargy, diarrhea, or refusal to eat or drink, it is wise to seek immediate veterinary attention. The vet can determine the underlying cause and provide appropriate treatment to ensure your dog’s well-being.
7. How can I stop my dog from eating everything in the garden?
To prevent your dog from eating everything in the garden, there are several measures you can take. Firstly, ensure that your dog has a balanced and nutritious diet, as their cravings may be due to dietary deficiencies. Secondly, consider creating a designated play area for your dog away from the garden, and provide them with plenty of toys and mental stimulation to keep them occupied. Additionally, it’s important to train your dog to understand basic commands like “leave it” or “drop it” to redirect their attention away from garden items. Lastly, if necessary, you can utilize barriers or repellents to safeguard specific areas of the garden. Consistency, positive reinforcement, and regular exercise are key for a well-behaved and satisfied dog.
