    Wow, very helpful details. I had never thought that “inoffensive Chamomile” could be somehow harmful. I would pay more attention next time. 

    I had some unexpected cases in the past with my dog, but fortunately not bad and for a very short period of time or mild symptoms. Never made the connection with plants and more with other type of “food”. Do you might have any other interesting details or medical studies etc.


    Stay safe!

      If your dog eats small amount of Chamomile he/she should be fine. I sometimes use organic chamomile tea for my dogs ears irritation and that is fine but if it is digested in large amounts or small amounts over long period of time it can be very harmful. I found doing research on this article very interesting and will add  more info soon!

    Never have I thought these common plants can be dangerous to our four-legged friend. I did not expect to see aloe vera, tomatoes and chamomile in your list. Truly glad you bring this to light as I believe many of us do not know.

    May I ask if it is just the tomato plant or including the tomato fruit? Curious to know.

    1. Gina says:

      Ripened tomato is fine for your dogs, it is just the green part of tomato plant you want to be careful with 🙂

    I had never really given it much thought that there are so many plants that are not good for dogs. I was aware of certain foods, like chocolate and cheeses, but not actual plants.We always grow our own tomatoes and our dogs would walk around it, but I’ve never seen them try and eat it. The same goes for flowers like daffodils. Our dogs eat grass on occassion and would steal nuts, but I’ve not seen them eat other plants. 

    This makes me curious to know if you think dogs have a natural instinct not to eat plants that would harm them? 

    1. Gina says:

      That is a good question. Wild canines do have the ability to smell poisonous plants and they keep away. However domestic dogs usually don’t or it is not fully functional. Also puppy will chew on anything and try anything so we must be careful.

    I didn’t know that Aloe Vera isn’t good for dogs. We have a lot of Aloe Vera plants here in our backyard where our dog is frequenting. We intentionally cultivated them for use in shampooing and in my attempt to regrow my thinning air (Alopecia). Thanks for this article, now I know that Aloe Vera is dangerous for our dogs, I am now planning to isolate the plant to a place where it is off-limit to our pets. Also, thanks for the list of spring plants that are dangerous for our pet dogs. I have now a checklist of these plants.

      I changed it now a bit in my content as the outer skin is dangerous so just watch your dogs! 🙂

    Though not exactly the plant per se, I do use the commercial aloe vera sap from time to time to apply on my dog’s wound. She gets moist dermatitis sometimes and I want to use more natural remedies than having to rely on oral and topical antibiotics all the time. The outcome has been good so far – no side effect whatsoever so it never crossed my mind that Aloe Vera could be toxic to dogs. Will have to read up more on that.

      Hello Cathy, I forgot to mention in my content that it is the outer skin that is dangerous for dogs! Thank you for pointing that out. I changed it now 🙂
