Hey Austin — if you've been taking your dog for a swim at one of our beloved local lakes, it's time to pump the brakes. Toxic blue-green algae has been spotted in Austin's waterways, and the scary truth is that it can be fatal to your pets — sometimes within hours of exposure.
Blue-green algae (technically a cyanobacteria, not actually algae) loves warm, slow-moving water — which, let's be honest, describes pretty much every Central Texas lake come summertime. When it blooms, it releases toxins that can cause liver failure, neurological damage, and even death in dogs. And here's the nightmare scenario: your pup takes a few laps of lake water on a hot August afternoon and you don't even realize anything is wrong until it's too late.
The rule of thumb local vets are pushing right now? If the water looks greenish, murky, or has a pea-soup texture along the shore, keep your animals out. Full stop. Don't let them drink from it, swim in it, or even lick their paws after wading through it.
Signs of exposure include vomiting, excessive drooling, seizures, and disorientation. If your dog shows any of those symptoms after a lake visit, head straight to an emergency vet — don't wait to see if it passes.
Austin's outdoor culture is one of the things we all love about this city, and we're not saying skip the lake days entirely. Just leave the pups at home or stick to dog-friendly splash pads and pools where the water is treated and monitored. Your dog's tail wags are worth protecting. Stay safe out there, Austin.
