Spider bites aren't very common in dogs, as spiders usually avoid humans and animals and dogs typically have a coat of fur that is harder for insects to get through, but they do still happen. In this post, our Fort Worth veterinarians explain the symptoms of spider bites on dogs and how they are treated.
What Does a Spider Bite Look Like on a Dog
Most spider bites are harmless, but at times, your dog can experience symptoms of illness as a result of an insect bite.
There are actually very few tell-tail signs to look out for to determine if your dog has been bit by a spider and how serious it is.
Non-Venomous Bites
Most spiders found in the Fort Worth area simply do not have enough venom to harm your dog or you. Their bites resemble mosquito bites in appearance and cause little discomfort to your dog. They can be treated naturally in a variety of ways, with the main focus being on itch relief. Some dogs may not even notice any discomfort.
Venomous Bites
The following are the two types of venomous spiders and their bites that Fort Worth pet owners should keep an eye out for:
Black Widow - Symptoms of a black widow spider bite can appear soon after your dog has been bitten. The bite itself is painful, causing swelling and redness in the affected area. Fortunately, only 15% of black widow spider bites are considered "dry," or non-venomous.
Brown Recluse - A recent bite from a brown recluse spider can be difficult to detect. They are usually painless, but they leave a red mark at the site. However, your dog will eventually develop a white blister with a bulls-eye or tissue destruction in the surrounding area.
In the case that your dog has been bitten by a spider after hours, seek after-hours emergency veterinary care.
How to Treat a Spider Bite on a Dog
If you believe your dog has been bitten by a spider, you need to contact your veterinarian immediately for an assessment.
If you see the spider that bit your dog, capture it in a jar so your vet can identify the venom and begin treatment as soon as possible. If you are concerned that the spider is dangerous, keep a safe distance and photograph it. Unfortunately, the effects of a spider bite do not always manifest themselves immediately; in this case, your vet will try to determine the type of bite based on the appearance of the area and any symptoms your pet is exhibiting.
Spider bite treatment in dogs varies depending on the spider but may include an antivenin for black widow spider bites, pain relievers, muscle relaxants, and IV fluids.
