Common Poisonous Plants in Your Home
The top 5 most common houseplants in America include the aloe vera plant, the snake plant, succulents, Peace Lilly, and English Ivy.
Are Any House & Garden Plants Safe for Dogs?
Aloe Vera Plant
The aloe vera plant is known worldwide for its healing properties. It’s easy to grow and is a perfect houseplant, especially if you’re prone to dry skin, mild burns or sunburns.
You might think that since it’s available in many drinks and products for people that it would be safe for dogs. Not so. Symptoms of aloe vera plant poisoning in dogs includes severe vomiting and diarrhea. This is particularly dangerous for puppies who may become dehydrated quickly, or dogs with compromised immune systems.
Snake Plant
The snake plant is toxic to dogs and creates symptoms such as nausea, vomiting, and diarrhea. Other names for the snake plant include, Golden Bird’s Nest, Mother-in-Law’s Tongue, or Good Luck Plant.
Peace Lilly
If you have a Peace Lilly in your home, be careful that your dog doesn’t take a bite out of it. If that happens, your dog could have irritation of the mouth, excessive drooling, trouble swallowing, or vomiting.
English Ivy
The English Ivy is also called Needlepoint Ivy, Sweetheart Ivy, and California Ivy. This plant can also cause gastrointestinal upsets similar. These include vomiting, stomach pain, excessive drooling, and diarrhea.
Are Succulents Poisonous to Dogs?
Succulents are not good for a dog to eat. The plant’s water-carrying properties make it sound safer to eat than it is. For dogs, the irritant comes from compounds within the plant.
A little exposure may cause some skin irritation; however, if your dog decides to eat the whole plant, it’s a worthwhile trip to the veterinarian clinic.
Side effects of succulents for dogs include everything from mild mouth irritation, to difficulty breathing. If your dog seems to be okay but you’re really not sure, it’s okay to contact Pet Poison control or your veterinarian for advice.
Petiquette and Dog Safety
If you plan to host social gatherings, make a point of taking care of your dog before guests arrive. Dogs tend to feel safe and secure in crates that are not too big (and obviously not too small).
Your dog should be able to stand up and turn around and there should be enough room for a bowl of water. Even a dog who is normally calm can get over-excited when company comes.
Just because your dog never chewed on plants before doesn’t mean your dog will never chew on plants.
The last thing you want is a guest asked, “Are poinsettias poisonous to dogs?” while your pooch chomps on some leaves.
No Table Scraps Please!
Even people who love dogs might not understand the consequences of feeding them table scraps. For that matter, your guest might not realize their unattended drinks could be lapped up by the dog.
If you’re not going to tuck your dog safely away while the party is in full swing, it’s okay to remind guests to be mindful of the dog.

Holiday Dog Danger Zones
Are poinsettias poisonous to dogs isn’t the only question to ask yourself. A simple Christmas tree can be very dangerous to adventurous dogs, especially artificial trees.
Artificial trees, just like the real thing, tend to weaken over time. The needles fall out and mini-lights loosen. Dogs are drawn to trees just as much as cats are. Hazards include swallowing sharp, artificial needles. When this happens, your dog is exposed to PVC (polyvinyl chloride), a cancer-causing compound found in consumer products.
Christmas tree ornaments shatter easily, leaving sharp pieces for your dog to swallow or step on. Have you ever tried to stop your dog’s paw from bleeding? It’s not easy.
Chocolate Toxicity in Dogs
Poinsettia plants are the least of your worries over the holidays. Chocolates tend to accompany social gatherings, but chocolate is toxic for dogs. In fact, the consequences of your dog eating chocolate is likely more dangerous than whether or not they a piece of poinsettia.
The two naturally occurring ingredients in chocolate are caffeine and theobromine. Dogs are unable to metabolize these stimulant compounds. It is the build-up of stimulants in the dog’s body that create toxicity.

At the End of the Day
While poinsettias aren’t considered poisonous, your dog might experience some tummy upset and mild symptoms if he/she decides to snack on the plant.
The bigger dangers in your house could be the everyday plants on the windowsill. Christmas trees, ornaments, packaging, etc., are all potential dangers. The last think you want is for your dog to need emergency surgery to remove tinsel from their body.
