10 Things In Your Home That Can Kill Your Dog


Dogs are very curious animals and as omnivores and natural scavengers, can get into and eat just about anything. However, there are many toxic substances found in your home that could potentially kill your dog. The following is a list of ten common household substances that you should make sure to keep out of your dog’s reach.

  1. Antifreeze: Many people do not realize it, but common antifreeze kills many pets each year. It smells and tastes very sweet to your dog and is very appealing to him. Ethylene glycol is toxic however, and each winter, many animals are killed by it. Symptoms of toxicity include seizures, vomiting, stumbling and lethargy leading to kidney failure. Make sure to keep your antifreeze out of your dog’s reach. If you suspect that your dog has ingested antifreeze, take your dog to the veterinarian immediately.
