My Dog Got Bit by Another Dog: Treating Infected Bites, Swelling & Puncture Wounds

Behavior & training
Two dogs engage in a tense confrontation on green grass, with one appearing to bite the other near its neck or shoulder – this concerning interaction could potentially lead to puncture wounds, infection, swelling, or behavioral changes that would require prompt treatment to prevent complications from the dog bite.

Your heart sinks as you hear the growl, followed by a yelp. In that split second, the carefree afternoon at the dog park transforms into a crisis: my dog got bit by another dog. You're not alone in this frightening experience. With nearly 4.5 million dog bites reported annually in the United States, many of these incidents involve dogs biting other dogs. 

The moments after your dog has been bitten can feel overwhelming. You're worried about pain, infection, and how this traumatic event might affect your furry family member emotionally. Knowing what to do next—from identifying the severity of the wound to proper treatment—can make all the difference in your pet's recovery. Let's walk through everything you need to know to help your four-legged friend heal physically and emotionally. 

Why Do Dogs Bite Each Other? 

Before diving into treatment, it helps to understand why these incidents occur. Dogs rarely bite without reason, and recognizing these triggers can help prevent future encounters. Fear or defensive reactions often occur when a dog feels threatened or cornered in an uncomfortable situation. Some dogs display resource guarding behaviors with food, toys, or even their human companions, which can lead to aggressive responses if another dog approaches. 

Play that escalates beyond comfortable boundaries is another common scenario, especially among dogs with different play styles or energy levels. Territorial behavior, particularly around a dog's home or yard, can trigger protective responses toward unfamiliar dogs. Dogs experiencing pain may also bite reflexively if touched in a sensitive or injured area, even if they're normally gentle. 

Perhaps most importantly, dogs with lack of proper socialization training often don't understand appropriate canine communication, leading to misunderstandings that can escalate to biting. Understanding these triggers doesn't excuse the biting dog's behavior, but it provides context that can help you avoid similar situations in the future. Dogs communicate through body language long before resorting to teeth, so learning to read these signals is your first line of defense. 

First Things First: Stay Calm and Separate the Dogs Safely 

When your dog gets bit by another dog, your immediate response matters. Here's what to do: 

  1. Remain calm—dogs pick up on your energy, and panic can escalate the situation 

  2. Don't place your hands between fighting dogs—this is how human bites often occur 

  3. Create a distraction by making a loud noise or using a water hose if available 

  4. Use a barrier like a large stick, chair, or blanket to separate the dogs if necessary 

  5. Once separated, secure both dogs in different areas before attempting to assess injuries 

  6. Exchange information with the other owner, including vaccination records 

Remember, your safety comes first. Even your own dog may accidentally bite you when in pain or distress. Having a well-stocked canine first aid kit with gauze, antiseptic wipes, and bandaging materials ready at home—and a portable version in your car—can make all the difference during those critical moments after an incident occurs.  

If you cannot safely separate the dogs, call for help from bystanders or animal control. Professional assistance is always better than risking injury to yourself. 

What to Look for in Assessing the Dog Bite Wound 

What does a dog bite look like on another dog? This varies depending on the severity and location of the injury: 

  • Puncture wounds: Small holes that penetrate deep into tissue, often appearing deceptively minor on the surface but potentially causing serious damage underneath. 

  • Lacerations: These present as torn skin or jagged wounds that may bleed profusely and are more visibly concerning. 

  • Crushing injuries: Tissue damage without breaking the skin, often causing bruising and swelling. More superficial abrasions remove the top layer of skin but typically don't penetrate deeply.    

  • Abrasions: Surface scrapes that remove the top layer of skin 

Dog bite marks often appear as a pattern of puncture wounds that match a dog's dental arcade. Carefully part your dog's fur to examine the full extent of any injuries, paying special attention to the neck, face, and legs—common targets during altercations. 

Don't underestimate small wounds. A dog puncture wound can be particularly dangerous because it creates a deep, narrow channel that seals quickly on the surface, potentially trapping bacteria underneath. This makes infection a serious concern even with seemingly minor injuries.

When to Call the Vet in Cases of Dog Bite 

While it may be tempting to monitor minor-looking injuries at home, veterinary evaluation is crucial in most cases. Contact your vet immediately if the wound is actively bleeding or gaping. If your dog was bitten by another dog and is swelling around the injury site, this indicates inflammation that needs professional assessment. Multiple puncture wounds always warrant veterinary attention, as do bites near sensitive areas like the eyes, throat, chest, or abdomen.  

Pay close attention to your pet's mobility—if your dog is limping or unable to put weight on a limb after a bite, internal damage may have occurred. If your dog got bit by another dog and is acting weird—showing lethargy, aggression, or unusual quietness—these behavioral changes could indicate pain or shock. Always seek veterinary care if the other dog's vaccination status is unknown or if your dog seems to be in significant pain. 

Even if the wound appears minor, remember that what you see on the surface may not reflect the extent of damage beneath. Puncture wounds can damage muscles, tendons, and even internal organs depending on their location and depth. When in doubt, consult your veterinarian. Early intervention can prevent complications and give your pet the best chance for a full recovery. 

What the Vet Will Do: Professional Dog Bite Treatment for Dogs 

When you arrive at the veterinary clinic, the team will implement a thorough examination process to care for your injured pet:  

  1. Assessment of vital signs to check for shock or severe pain 

  2. Wound evaluation to determine the full extent of injuries 

  3. Cleaning and flushing of the wound to remove bacteria and debris, which is a crucial step in preventing infection 

  4. Possible sedation for thorough examination of painful areas 

  5. X-rays or ultrasound imaging to visualize structures beneath the skin, if internal damage is suspected 

  6. Surgical exploration and repair, if necessary, in case of deeper wounds or extensive tissue damage 

For dog bite treatment, dogs typically receive antibiotics to prevent infection, pain medication for comfort, and possibly anti-inflammatory drugs to reduce swelling. Your veterinarian will also discuss whether the wound should be left open to drain or closed with sutures—this decision depends on several factors including the wound's location, depth, and how long ago the bite occurred. Follow your vet's post-treatment instructions carefully to ensure optimal healing and recovery. 

Cleaning the Bite Wound at Home (If Instructed by Vet) 

If your veterinarian approves home care for minor wounds, follow these steps carefully: 

  1. Begin by gently trimming the fur around the wound using scissors (if safe to do so) to prevent hair from entering the wound and to allow better visualization during cleaning. 

  2. Use a warm saline solution to gently flush the area (1 teaspoon salt to 2 cups warm water) to remove debris and bacteria 

  3. Apply only veterinary-approved antiseptic like diluted chlorhexidine (never use alcohol or hydrogen peroxide), as these can damage tissue and delay healing. 

  4. Use an E-collar or dog cone alternatives to prevent your dog from licking the wound during the healing process. 

  5. Follow your vet's instructions for bandaging, as improper bandaging can create a moist environment that promotes bacterial growth. 

Monitor the wound several times daily for signs of dog bite infection. 

Preventing Dog Bite Infections 

Infected dog bites are dangerous because a dog's mouth contains numerous bacteria that can cause serious infections. Left untreated, these infections, even seemingly small ones can spread to surrounding tissues and even enter the bloodstream. 

Signs of an infected dog bite wound typically develop within 24-48 hours and include: 

  • Increased pain, swelling, or redness around the bite site 

  • Heat radiating from the area  

  • Pus or discharge coming from the wound 

  • Red streaks extending from the wound indicating that infection is spreading through the lymphatic system 

  • Fever or lethargy, which are systemic symptoms suggesting that the infection may be affecting your dog’s entire body 

If you notice any of these symptoms, contact your veterinarian immediately. Prompt treatment of dog bite infection is significantly important to prevent serious complications that could endanger your pet's health or even their life. Never adopt a "wait and see" approach when signs of infection are present.

How Pet Insurance Can Help in Case of Dog Bites 

When accidents like dog bites happen, the last thing you want to worry about is the cost of care. Emergency veterinary visits can be expensive, with costs ranging from hundreds to thousands of dollars depending on the severity of the injury. Treatment for a serious dog bite might include emergency care, diagnostic imaging, surgery, overnight hospitalization, and weeks of medication. Veterinary care for a serious bite could range from roughly $3,000 to $15,000 or more, depending on the specifics, a situation where pet insurance can provide crucial financial support

Choosing a reliable pet insurance plan for your dog can help cover unexpected injuries like dog bites, potentially including emergency care, medications, surgeries, and follow-up visits at any licensed veterinarian in the U.S, depending on how you customize your policy. Having a full coverage pet insurance plan in place before an incident occurs means you can focus on your pet's recovery rather than difficult financial decisions during an already stressful time. 

Many pet parents don't realize that even well-socialized dogs can be involved in biting incidents—either as the victim or the aggressor.

How to Help Your Dog Heal from Dog Bites 

Recovery from a dog bite involves more than just wound care and healing, your pet may need emotional support as well. Create a quiet, comfortable space where your dog can rest undisturbed, away from other pets and household activities. This sanctuary allows for stress-free healing and helps your dog feel secure after a traumatic experience. 

Limit physical activity according to your vet's recommendations to prevent reopening wounds or causing additional strain on injured tissues. Even if your dog seems energetic, proper rest is important for complete recovery. Administer all medications as prescribed, even if your dog appears to be feeling better. Completing the full course of antibiotics is particularly important to prevent resistant infections. 

Use gentle, positive reinforcement when handling the injured area to help reduce anxiety and build trust. Your dog may be sensitive or fearful about having certain areas touched after an injury, and patience is key to helping them overcome this fear.  

Some dogs develop fear or aggression toward other dogs after being bitten. This is a normal response to trauma and often requires time and positive experiences to overcome. If these behavioral changes persist for more than a few weeks, consider consulting with a professional dog trainer or animal behaviorist for specialized guidance. 

How to Prevent Future Dog Bites 

While not all dog bites can be prevented, you can significantly reduce the risk with thoughtful management and training, and by following these strategies: 

  • Proper socialization training for your dog from an early age with controlled, positive interactions. 

  • Learning to recognize canine body language that signals discomfort or aggression. 

  • Identifying and avoiding known trigger situations for your individual dog 

  • Using proper leash control in public settings gives you the ability to guide your dog away from potential conflicts 

  • Respecting other dogs' space and not allowing your dog to approach unknown dogs without permission 

  • Avoiding dog parks during peak hours if your dog shows anxiety in crowded settings 

Pay attention to subtle warning signs that a dog might bite: stiff body posture, raised hackles, ears pinned back, whites of eyes showing (whale eye), growling, or showing teeth. If you notice these signs, calmly remove your dog from the situation.  

Healing and Moving Forward After a Dog Bite 

When your dog gets bit by another dog, quick action and proper care make all the difference. From immediate first aid to professional veterinary treatment and attentive home care, each step contributes to your pet's complete recovery. 

Remember that healing involves both physical wounds and emotional well-being. Some dogs bounce back quickly from these incidents, while others may need more time and patience to regain their confidence around other dogs. Respect your pet's individual healing process and never force interactions that cause anxiety.

By understanding why dog bites happen, how to identify and treat wounds properly, and implementing strategies to prevent future incidents, you're well-equipped to protect your furry family member.
