Tips for Protecting Your Dog


The best way to protect your dog from poisonous plants inside and outside the home is to remove them entirely. In the house, you may be able to get away with simply moving the plant onto a higher shelf or placing it in a room to which your dog does not have access. Outside, things can get a little tricky – you may need to either remove the plant or put up a fence around it that your dog cannot get through. If you are worried about your dog getting into toxic plants that are outside the range of your property your best bet may be to fence your yard and to only let your dog out of the yard when he is on a leash and under your supervision.


Protecting your dog from harmful and toxic plants is not difficult if you know what plants to look for and if you make an effort to keep your dog from coming into contact with them. Dogs do not always know that something has the potential to cause them harm, so it is up to you to protect him from plants that could be toxic.
