Is Preen Dangerous For Pets?

Yes, preen can be pretty much dangerous to pets. Pet owners need to be aware that the chemicals in preen can be harmful to pets. Glysophate, one of the major makeup of weed killers, targets the weed’s growth. It stops the growth and proceeds to destroy the plant.

Glysophate may not be precisely toxic to pets, but coupled with other ingredients, the toxicity level is relatively high. However, it can harm pets when they sniff or ingest the weed. It is advised that pet owners shouldn’t allow their pets around the lawn when they use preen.

As this could mean putting their health at risk. Pets are prone to getting sick when they come in contact with preen; it could trigger vomiting, lethargy, diarrhea, and convulsions. Keeping them out of the lawn or garden is best until the preen is completely dried off.

Also, when taking them for a walk, avoid taking them to areas sprayed with preen. If your pet accidentally comes into contact with preen, immediately take them to the vet.
