toxic-foods-for-dogs-toxic-plants-for-dogs

Grapes and raisins can be tasty to human, but they are very danger to your dogs

Science hasn't yet found out why grapes and raisins are very toxic to dogs, but they do know ingested (even in small amounts) can cause sudden, acute kidney failure. Along with this is the lack of urine output.

According to PetMD not all dogs will be affected by the eating of one grape or raisin, but don't take the chance, keep Fido away from this fruit.

Citrus

toxic-foods-for-dogs-toxic-plants-for-dogs-1

Citrus can do harm to your dogs' stomachs

Although, the "meat" of citrus fruits can cause stomach upset in dogs, the main toxicity is found in the peel, stems, leaves and seeds. These all contain high levels of citric acid and essential oils that can harm your pet's central nervous system; the brain and spinal cord.

Cherries

toxic-foods-for-dogs-toxic-plants-for-dogs-18

The seed in cherries contains cyanide

It's not so much the cherry itself that is toxic to dogs (although, it can cause digestive troubles) it's the pit. This seed contains levels of cyanide that will be harmful to your dog if chewed or swallowed. Not only can the pit poison your pooch, but it can also become lodged in its throat, posing a choking hazard.

Currants

toxic-foods-for-dogs-toxic-plants-for-dogs-19

Currants can cause severe vomiting, diarrhea and even anorexia in your dogs

This small round fruit comes in the white, purple or red variety. They are usually found in baking, but can be used in a variety of prepared meals. Just like raisins, currants can cause acute renal failure in your dog.

In addition, your pet can have severe vomiting, diarrhea and even anorexia. If you have a currant bush in your yard, be sure to always pick up the fallen fruit to ensure your dog's safety.

Apricots

toxic-foods-for-dogs-toxic-plants-for-dogs-2

Apricots can make your dog breath difficultly

All parts of the apricot fruit is toxic to dogs. This includes the stems, leaves and pits. As with other pitted fruits, the large apricot seed contains enough cyanide in it to do serious harm to your canine. 

Ingesting seeds that contain cyanide can lead to the breakdown of the important enzyme that is responsible for oxygenating your dog's cells. This can result in your dog having difficulty breathing, dilated pupils and even death.

Apple Seeds

toxic-foods-for-dogs-toxic-plants-for-dogs-20

Keep your dog stay away from apple seeds

The same cyanide properties found in other seeds and pits are also found in apple seeds. If you want to feed your dog the occasional slice of apple, be sure to remove the seeds, stem and core.

Persimmons

toxic-foods-for-dogs-toxic-plants-for-dogs-3

Persimmons contain cyanide

Although the persimmon berry (yes, it's technically a berry) is not toxic to your dog, it can cause stomach upset. Plus, once again, the seed is the dangerous culprit. The persimmon pit can pose a choking hazard and may inflame your dog's small intestine. Plus, it too is filled with cyanide

Peaches

toxic-foods-for-dogs-toxic-plants-for-dogs-21

Like apple, seeds of peaches are also toxic

Another pit-fruit is the peach. As with other fruits with these large seeds, they do contain cyanide. And, of course, the larger-nature of the peach pit could easily choke your dog.

Plums

toxic-foods-for-dogs-toxic-plants-for-dogs-22

Plum contains a large amount of vitamins, but its seeds are toxic

The last fruit on our toxic list is the plum. This (again) contains a pit which does have cyanide in it. Avoid the plum seed as it can also cause a choking hazard and an obstruction in the digestive tract of smaller dogs.

What Can I Do If My Dog Ingests Something Toxic?

toxic-foods-for-dogs-toxic-plants-for-dogs-17

What should you do if your dog ingest something toxic?

Before you find yourself in this situation, here are some tips every pet parent should know when it comes to canine poisoning.

Tip #1 - Don't Panic

Even though your emotions may be running high, the best thing you can do if your dog has ingested a toxin is don't panic. Remain calm and assess the situation. Examine your pooch for obvious signs of symptoms like vomiting, diarrhea, restlessness, legarthy etc.

Tip #2 - Call Your Veterinarian

toxic-foods-for-dogs-toxic-plants-for-dogs-15

Keep calm and call the veterinarian as soon as possible

Regardless of what your dog ate, it's always better to err on the side of caution. Call your veterinarian to make an emergency visit ASAP.

Tip #3 - Gather the Evidence

Before you leave for the vet's office, gather up all the evidence you can about the toxic food/plant/object your dog has eaten. You will also want to establish a time frame of when the toxin was consumed and how much was eaten (if possible).

Your vet will also want to know your dog's weight, age and if he is taking any medications. All this information will give your vet a better idea as to how to begin treatment. Depending on what was ingested your vet may want you to induce vomiting; however, NEVER do this without the recommendation of your dog's doctor.

Tip #4 - Be Honest With the Veterinarian

Some pet parents may be reluctant to be totally honest when it comes to illegal substances such as street drugs, because of legal ramifications. This puts your dog at a higher risk of death, so always give all the information you have to help your pet get the most accurate treatment it can.

Tip #5 - Know What to Expect at the Vet's Office

Depending on what your dog has ingested, the treatment can vary between inducing vomiting or surgery.

Most often if the toxin can be ejected, your vet will give your pup a special injection that will cause him to vomit. After the stomach contents is emptied, your vet may also give your dog an activated charcoal which will neutralize any toxin that may be circulating throughout your dog's blood stream.

Once these procedures has been followed, your vet will most likely want to keep your dog at the clinic for an additional 24 hours to flush its system with intravenous fluids.

toxic-foods-for-dogs-toxic-plants-for-dogs-16

Your dog can be kept in the clinic for 24 hours to be observed

If your dog has swallowed something large, it may require surgery to remove it. This can be done by surgically opening your dog's abdomen to remove the object before it has a chance to go through the intestinal tract.

If the object that was swallowed is small, your vet can use a procedure using an endoscopy. This is a small camera that is inserted down your dog's throat and to his stomach.

Once there your vet can see exactly where the foreign object is and can then remove it with a small hook on the end. The hook grabs the object and pulls it back through your dog's throat and mouth.
