In Part 3 of our 4-part series on blue-green algae, professor, decontamination expert, and FEMA Canine Search Specialist Dr. Erin Perry gives us best practices for decontaminating your dog when you suspect exposure.

What considerations are there when decontaminating your dog?

Best practices for decontamination include consideration of route of exposure, available supplies and time to treatment. Potential routes of exposure include ingestion, inhalation and direct contact. Mostly commonly dogs are thought to ingest the toxins from drinking contaminated water but inhalation and dermal contact are also implicated.  Due to the dangerously high toxicity associated with certain cyanobacteria, rapid decontamination is necessary for exposed dogs. Poisoning may occur within minutes or days depending on the type and accumulation of cyanotoxin present.

Handler

Why is decontamination important?

If you believe your dog has been exposed he/she should be monitored and self-grooming behaviors prevented until complete decontamination can occur. Canines will commonly lick paws, lower legs, flank and abdominal areas following vigorous activity. If canines attempt to self-groom prior to complete washing (i.e. in the car), steps should be taken to interrupt and stop this behavior in order to prevent further ingestion of the cyanotoxins which may be present. A muzzle can be used to prevent self-grooming but only if heat stress is not a concern and respiration is not impaired.

How do I decon my search dog?

Canines exposed to contaminated water must be immediately and thoroughly washed with copious amounts of clean water to remove the cyanobacteria that produce the dangerous toxins.

Gross Decontamination

If dog-washing facilities are not immediately available rinse the canine with as much clean water available (gross decontamination) then seek full washing facilities immediately.

Technical Decontamination?

EVERY area of the dog must be thoroughly washed using a veterinary dermatological shampoo with an antibacterial agent. Use a washcloth to avoid getting soap in the eyes and nasal passages.

Washing dog paw with gloves on

Are there any safety considerations for the handler?

Handlers should utilize protective clothing and gloves during the wash procedure to prevent skin exposure.

What about my gear?

All clothing, leashes, collars, kennels or other equipment suspected of contamination should be thoroughly washed with an antibacterial agent prior to reuse. Porous or cloth toys (tennis balls, canvas tug toys, etc.) should be disposed of after suspected contamination.

Any final words to share with your fellow handlers?

As a handler who has experienced the devastation that occurs when your partner is exposed to poisonous compounds, please remember that this is a time sensitive issue.  Do not delay decontamination or seeking veterinary treatment.  Your partner’s life may depend on it.
