You can help avoid the dangers presented by poisonous plants for dogs by knowing what they are and what kinds of effects they trigger on your pet. Although dogs can be naturally averse to such plants, there are times when they unwittingly get into contact with them or even eat them out of curiosity or fun. Some of these dogs may even be ignorant of these plants particularly puppies. These plants can cause from mild to lethal toxic effects so it is important to know what they are. Your knowledge can help save you and your pet from future health problems and heartaches.
Dogs are naturally playful and they like to wander around especially in areas that they are not that familiar with. Hence, it is very common to see dogs especially those with a natural prey drive to roam around forested areas or even wander out of the way whenever they meet grassy patches of land.
There are plants that we know are not safe even for humans but there are also less familiar ones which your dog can accidentally eat that you may not be aware of. To help you avoid such situations, here is a list of poisonous plants for dogs that you need to know about.

You will know if your dog has ingested belladonna if he or she shows the following symptoms:
- Loss of appetite

You will know that it is rhubarb with its red and fleshy stalks as well as its broad green leaves and red midsections.
What makes this plant so toxic is its leaves that contain oxalic acid which is a very corrosive type of acid. It damages blood vessels that it passes and it damages organs more important the kidneys. These damages are often irreversible and can cause fatalities if the leaves are ingested in large amounts. Signs of rhubarb poisoning include:
