Hello. My male lab (aged 8) was just bitten on the face in the snout & mouth area by a huntsman (rain spider) as he is black I cannot see the bite area. Is this spider dangerous to my dog? Is there anything I need to look out for? Kelly

Hi Kelly, Are you 100% sure he was bitten? Hunstman spiders rarely bite. They do possess some venom, and if bitten, the area around the bite may get inflamed and/or infected. Symptoms vary depending on the type of spider and amount of venom released when bitten. Here is a list of possible symptoms to look for: General problems: Weakness/Lethargy Muscle or joint pain Seizures Increased heart rate Trouble breathing Drooling Diarrhea Vomiting Trouble walking/standing At the location of the bite: Swelling Redness Pus/Infection If you notice any abnormal symptoms then get him to your vet for an exam.
