There’s one particular yard I’m careful to walk by because their yard has sandburs. This a type of grass with sharp spiny burs. They are literally a pain to remove from your dog’s fur. Both you and your dog will get painfully poked trying to remove them. I found a slicker brush is the easiest way to get them out. Try to get them out right away as they will get increasingly entangled making them difficult to remove. I pulled this plant out of their yard and will destroy it so no harm comes to Hoshi.
