Why Do Some Dogs Have a Higher Tendency to Dig into Trash Cans or Dumpsters?

Have you ever wondered why some dogs have a higher tendency to dig into trash cans or dumpsters? Dogs have a natural instinct to scavenge for food, and trash cans and dumpsters are a tempting source of food for them. However, some dogs are more prone to this behavior than others.

There are several reasons why some dogs may have a higher tendency to dig into trash cans or dumpsters. One reason is that they may not be getting enough food or nutrients in their regular diet. Another reason is boredom or lack of stimulation, which can lead to destructive behavior such as digging into trash cans. Additionally, some dogs may simply have a stronger sense of smell and are more easily tempted by the odors coming from the trash.

Canine Instincts

It’s important to understand that dogs are descendants of wolves, and their instincts are still very much intact. One of those instincts is the drive to scavenge for food. In the wild, wolves have to hunt for their food, but domesticated dogs have easy access to food in our homes. However, their scavenging instinct still remains, and they may try to find food in places like trash cans and dumpsters.

Another instinct that may drive dogs to dig into trash cans and dumpsters is their territorial nature. Dogs may view the area around their home as their territory, and they may feel the need to protect it from intruders. When they smell something in the trash, they may see it as a potential threat and feel the need to investigate and protect their territory.

Additionally, dogs have a highly developed sense of smell, and they are able to detect even the faintest of odors. This means that they can smell food scraps from a distance, and they may be drawn to the scent of food in the trash. Once they have discovered that they can find food in the trash, they may continue to try to dig into it in the future.

Behavioral Issues

There are several behavioral issues that can cause a dog to dig into trash cans or dumpsters. Here are a few:

  • Boredom: Dogs that are bored can become destructive and turn to digging through the trash as a form of entertainment. It’s important to provide your dog with plenty of physical and mental stimulation to prevent boredom.
  • Separation Anxiety: Dogs with separation anxiety may become anxious and destructive when left alone. They may dig through the trash as a way to cope with their anxiety.
  • Hunger: Some dogs may dig through the trash because they are hungry and looking for food. This can be especially true for dogs that are not getting enough food or are not being fed on a regular schedule.
  • Curiosity: Dogs are naturally curious animals and may dig through the trash simply because they want to explore and investigate the contents.

If your dog is exhibiting any of these behavioral issues, it’s important to address them as soon as possible. Providing your dog with plenty of exercise, mental stimulation, and a regular feeding schedule can help prevent some of these issues. Additionally, working with a professional dog trainer or behaviorist can help you identify the root cause of the problem and develop a plan to address it.

Nutrition and Diet

A dog’s diet plays a crucial role in their overall health and behavior. A poor diet lacking essential nutrients can lead to cravings for certain foods, including those found in the trash. Dogs may also develop a habit of scavenging for food if they are not fed enough or on a regular schedule.

It’s important to provide your dog with a balanced diet that meets their nutritional needs. Feeding them high-quality dog food, and avoiding table scraps and unhealthy human foods, can help reduce their desire to seek out food in the trash. Additionally, providing your dog with treats and toys can help satisfy their natural chewing and gnawing instincts.

If you suspect that your dog’s diet may be contributing to their trash-digging behavior, consult with your veterinarian. They can help you determine the best diet for your dog based on their age, breed, and overall health.

Here are some tips for feeding your dog a healthy diet:

  • Choose a high-quality dog food that is appropriate for your dog’s age, breed, and activity level.
  • Avoid feeding your dog table scraps and unhealthy human foods, such as chocolate, onions, and garlic.
  • Provide your dog with healthy treats, such as carrots or apple slices, instead of processed dog treats that may be high in calories and additives.
  • Monitor your dog’s weight and adjust their food intake as needed to maintain a healthy weight.

Training and Management

If your dog has a habit of digging into the trash can, it’s important to address the behavior as soon as possible. Here are some tips for training and managing your dog’s behavior:

  • Keep trash cans and dumpsters securely closed and out of reach from your dog.
  • Consider using a trash can with a locking lid or a heavy-duty dumpster with a lid that is difficult for your dog to open.
  • Teach your dog the “leave it” command and use it whenever they try to approach the trash can or show interest in it.
  • Provide your dog with plenty of toys and chews to keep them occupied and prevent boredom.
  • Supervise your dog when they are in areas with access to trash cans or dumpsters.
  • Use positive reinforcement training techniques to reward your dog for good behavior and discourage bad behavior.

It’s important to remember that training and managing your dog’s behavior takes time and patience. Consistency is key, and it’s important to remain calm and avoid punishing your dog for bad behavior. With the right training and management techniques, you can help your dog break the habit of digging into the trash can and keep them safe and healthy.


While it is normal for dogs to be curious about their surroundings, some dogs have a higher tendency to dig into trash cans or dumpsters. This behavior can be due to several reasons, including boredom, anxiety, and lack of proper training.

Owners can take several steps to prevent their dogs from digging into trash cans or dumpsters. These include providing enough physical and mental stimulation for their dogs, keeping trash cans and dumpsters securely closed, and training their dogs to obey commands such as “leave it” or “drop it.

It is also important to note that certain breeds may have a higher tendency to dig into trash cans or dumpsters due to their natural instincts. For example, breeds such as Beagles and Terriers were originally bred for hunting and may have a stronger drive to explore and scavenge.

Overall, understanding the reasons behind a dog’s behavior is crucial in preventing unwanted actions. By providing proper training, stimulation, and a safe environment, owners can help their dogs overcome their natural instincts and live happy, healthy lives.
