Blue-green algae is one of the most dangerous warm-weather risks many dog owners still don’t know enough about. ⚠️🐶
This toxic bacteria can grow in:
• ponds
• lakes
• slow-moving water
• standing water
It often appears as:
• green slime
• paint-like scum
• green surface streaks
• pea soup-looking water
Even small amounts can be deadly if ingested.
Dogs may be exposed by:
• drinking contaminated water
• swimming
• licking fur afterward
Symptoms can appear very quickly and may include:
• vomiting
• diarrhea
• weakness
• drooling
• seizures
• difficulty breathing
• collapse
If exposure is suspected, immediate veterinary care is critical.
When in doubt, it’s safest to keep dogs away from suspicious water entirely.
