Collapse
Some toxins are more damaging than others, and if your dog sniffs the wrong ones, he might collapse before any other sign sets in.
This usually applies to toxins that affect circulation and heart function, like prescription drugs, illicit substances, and even chemicals that might appear after plant ingestion or snake bites.
If your dog suddenly collapses right in front of you, this is definitely an emergency, and don’t hesitate to bring your dog to the closest vet.
Trouble breathing
Toxins that harm the respiratory system might be at fault for causing wheezing, difficulty breathing, shortness of breath, and even slowed breathing.
You might also notice that the gums turn blue. If that’s the case with your pup, then treat it like an emergency and get him to the closest vet.
