If your dog has bruising, blood in their stool, nosebleeds or anemia they have most likely gotten into rat or mouse poison. However, if they’ve gotten into your garden or kitchen and eaten too much onion, garlic, sweet clover or bracken fern they could also suffer from anemia and could even die.

This list is long and includes the following: antidepressants, alcohol, aspirin, drain cleaners, dishwasher soap, gasoline, marijuana, flea repellents, tobacco, furniture polish and strychnine.

What Foods Are Dangerous to Dogs?

In 2011, dogs eating toxic foods was the #1 cause of dog poisoning. We know it’s impossible to watch your dog 24/7, but if you know there’s something your dog shouldn’t get into you should put it up high in a cupboard, or somewhere else you know they can’t reach. Dogs eating chocolate or grapes is preventable. Be cautious of where you place your food and check out our extensive list of foods dogs should not eat.

Has your dog every gotten into something they shouldn’t have?

Growing up, Kimberly used to get the sniffles when she was around dogs. Thankfully, she grew out of her allergy and is now able to play and snuggle with dogs as much as she wants! She adopted Sally, a four-year-old hound mix, in early 2017, and at the end of 2017 she adopted Kopa, a one-year-old treeing walker coonhound. She and her husband are loving life as pet parents.

My pretty girl Bella (blue eyes) is (was) an All American Pitt. Not what most people think , my pitt baby was very friendly, never knew a stranger. Anyways, my neighbor hated my baby, then one day I noticed she was sick… 5 days total. 1st day she was throwing up, not wanting food, not even her favorite TREATS! Which was really odd…she acted that way for 3 days, then it got worse. 4th day she started to spew rotted smelling blood when she done number one or number two. Now it was a lot worse at number 2. I called the vet but they were all closed except one that was a 2 hr drive which would have been closed when I got there. So I got everything I needed for her ready for the vet first thing the next morning, which was too late. The big dreadful day I was sitting in the living room floor with her in my arms I could hold her head a certain way and she would be able to breath but she would seize out too. I held her for 10 minutes before she took her final but last breath. I need a piece of mind here, what was it?

I’m so sorry for your loss Lola. I’m sure Bella appreciated having you with her during her final hours and having you hold her as she took her last breath. Unfortunately, I cannot say what caused her this illness. Perhaps talking with a vet could help clear some of it up for you. Thank you for sharing your story with us and know that our thoughts are with you.
if you can prove they poisoned your dog you can take legal action against them. try to get them to admit it and record it. and try to find out details like what kind of poison they used and how your dog got it. these jerk need to be stopped.
It sounds like parvo.. If u missed her yearly vaccination she is highly likely to get that disease. Parvo it’s highly contagious between dogs. Also parvo has a distinctive smell in the blood like u were mentioning.

This is some great information, and I appreciate your point that seizures can indicate poisoning in a dog. My dog had a short seizure yesterday, and it’s been a while since he last had one, so I’m not sure what caused it. I’ll definitely keep an eye out, and if he has another one, I’ll be sure to take him to the animal hospital to see what the problem is. Thanks for the great post!

As I sit here typing, I am watching my little Molly, a Bichon Frise, slowing dying. It’s breaking my heart because I can’t find a vet that will let me make payments for a visit and testing she needs. I am a 66 yr. old disabled senior and money is hard to find. She hasn’t held food down for a week, now nothing stays down, not even water that she was crying for at the onset. Two nights ago, she started vomiting black tarry substance and also her poo looks the same. It’s been almost non-stop vomiting (which is the only thing she stands up for now.) since last night. I’m wondering if she ate something poison on one of our walks. I called her Hoover before she got sick because she would eat any type of food and try to swallow it whole when I tried to get it. I live in a large apartment complex and have heard that animal-haters here have been threatening to poison the animals. Does anyone know how I can get her seen without all the money up front? Any information is appreciated. I rescued her off the streets and she brought me out of a major depression. I have sleep apnea too and she would bark when she noticed I stopped breathing in my sleep to wake me up. I promised her she would never be abused again and now I feel like I am the abuser. All I can do is cry for my baby, Molly. Prayers appreciated too.

Hello Karen, I hope Molly is doing better. Have you tried or contacted Animal Humane Society? If you call them & tell them your situation & Molly’s illness they can help or point you in the right Direction, there are a lot of non-profit organizations that assist with fund’s everywhere even in rural areas. There’s also always Social media you can start a “go fund me” account in which people,s friend’s etc.. donate money to you. On another note I’ve had to rush my dogs to the vets, sometimes emergency vet centers, at the time walking in there I didn’t have a dollar in my pocket however, I was never turned away, I simply explained that I would have to pay them in a week or two when I was paid, and sometimes i would have to tell them I couldn’t pay them the whole amount in one payment.
Hope she recieves the Med. Attention she needs:) sending warm furry hugs & thoughts
Alot of veterinarian offices offer care credit which is like a credit card you use to pay your vet bills
I hope your sweet baby got better
