No one likes the idea of spiders biting us or our pets in our homes. Most of the time, these creatures stay out of sight and don't bother us, but there are some cases where they will bite us or our canine companions. In this blog post, our Bonita Springs vets explain everything you need to know about spider bites on dogs and when you should seek medical attention.
What does a spider bite look like on a dog?
Spider bites on dogs can be challenging to identify, as they may resemble other insect bites or skin irritations. A spider bite on a dog appears as a small red bump or welt. Sometimes, the bite may have a small puncture mark at the center. As the bite area swells, it can become more noticeable. It’s essential to keep an eye on any unusual skin changes and monitor them closely.
What are the signs and symptoms of a spider bite on a dog?
Symptoms of a spider bite on a dog can vary depending on the type of spider and the dog's reaction to the venom. Common symptoms include:
- Swelling and redness around the bite area
- Pain or tenderness
- Itching or irritation
- Hair loss around the bite
- Blistering or necrosis (in severe cases)
In more severe cases, dogs may exhibit systemic symptoms such as:
- Fever
- Lethargy
- Loss of appetite
- Vomiting or diarrhea
- Muscle tremors or seizures
- Difficulty breathing
If you notice any of these symptoms, it's crucial to seek veterinary care immediately.
Can a spider bite be dangerous for dogs?
Yes, some spider bites can be dangerous for dogs. While most spiders are harmless, bites from venomous spiders like the Black Widow or Brown Recluse can cause severe reactions. Black Widow spider bites can lead to muscle pain, cramps, and neurological symptoms. Brown Recluse spider bites can cause significant tissue damage and necrosis. Immediate veterinary attention is vital if you suspect a venomous spider has bitten your dog.
How are spider bites on dogs treated?
If you suspect a spider has bitten your four-legged companion, contact your vet. They will advise you to take your pup to the nearest emergency vet clinic or suggest how you can treat a spider bite on your dog at home. Sometimes, they may even assure you that your dog doesn't require any treatment.
If you see the spider that bit your dog, capture it in a jar so your vet can identify the venom and start treatment promptly. If you are worried about the bite being very dangerous, keep a safe distance and take a photograph.
Unfortunately, the effects of spider bites may not become apparent until after the actual bite. In such instances, your vet will rely on the appearance of the affected area and the symptoms your dog is displaying to determine the type of bite.
Depending on the type of bite, treating a spider bite may involve administering antivenom, IV fluids, cleaning solutions, pain medications, or antibiotics. Applying ice packs can help reduce swelling and irritation. Clean the area using soap and water or create a paste with baking soda and water for non-venomous bites. Encourage your dog to refrain from excessively licking or scratching the affected area.
How quickly will my dog recover?
Non-venomous spider bites will heal in as short as two to three weeks. Even some venomous bites will heal in a month or so.
However, the most serious bites from black widows or brown recluses can take much longer to heal. With rapid response and ongoing treatment, your dog can fully recover from these bites within a few months.
