"Magoo was a big, playful Labrador retriever who
often got himself into sticky situations..."
So begins a story in the latest report from the ASPCA on
foods that may be toxic to dogs. It turns out that Magoo
got into the pantry and snagged himself about a pound
of raisins. He ate the whole thing, of course.
The ASPCA never mentions Magoo's fate. But they do
tell us that as little as a handful of raisins can impair a
dogs health and has been fatal for some. Ditto for the grape.
Who Knew?
Growing up, I regarded our family dogs as "the first cycle
of the dishwasher". They were good about waiting their
turn for whatever we left on our plates, and we weren't too
concerned about offering them "people food". It never
crossed our minds that our dogs health could be affected
by a few measly table scraps. What was safe for us, we
figured, was safe for our pets.
What's more, whenever I ate grapes, I liked to give one
or two to our German Shepherd "Tiffany". The grapes
always popped out of her mouth when she tried to bite
into them and Tiffany, ever the good sport, refused to
give up until she'd squashed each one into submission.
It guaranteed at least 60 seconds of harmless fun.
Tiffany was also fond of chewing gum (she chewed
it -- wrapper and all -- but didn't swallow it!) We had
the sugarless kind, which is often sweetened these
days with xylitol. Little did I know that I might have
been poisoning our family pet! (More on xylitol below).
Why are grapes harmful? As far as grapes and raisins go, no one is sure why
they're harmful. It's been confirmed that even grapes
grown without fertilizers or pesticides can be toxic to
dogs. But not to every dog, and not every time. It's
also not known whether small amounts eaten over a
long time period could have a cumulative effect.
What we do know is that the end result in nearly all
reported cases of grape or raisin toxicity is acute
kidney failure. (The term "acute" means that the
condition is severe and comes on quickly.) The dog
ultimately can't produce urine, which means they
can't filter toxins out of their systems -- a process
essential to life.
During the twelve-month period in which the effects
of grapes were studied, the ASPCA Animal Poison
Control Center handled 140 cases involving one or
more dogs. Over a third of the dogs developed
symptoms ranging from vomiting to kidney failure,
and seven dogs died. The ASPCA based their study
on reported cases, so naturally there may be cases
where a dogs health is entirely unaffected by eating
grapes. But until they know all the facts, the Society
advises against feeding pets grapes or raisins
in any amount.
An ounce of prevention
So, your dog just scored himself a big box of raisins.
What's a pet owner to do?
The first line of defense, if the grapes or raisins were
eaten recently, is to induce vomiting and administer
activated charcoal (it absorbs toxins in the GI tract).
Vomiting is also the first sign that your dog is in
trouble, so skip right to the activated charcoal if
vomiting has already occurred. (In a pinch you can
make your own activated charcoal by charring a
piece of toast until it's blackened and crumbles
easily.) Then call your vet right away.
Can't reach the vet? Call ASPCA
Poison Control: 888-426-4435
The vet will keep your dog on intravenous
fluids for at least 48 hours and monitor blood
chemistry daily. Normal blood work after 3 days
usually means your dog is in the clear.
Keeping a watchful eye out, of course, is the
best way to keep your pet out of trouble. Like
children, dogs (and other pets) have a knack for
getting into mischief when we're not looking.
It's Not Just the Grapes...
There are other foods your dog should be kept
away from, and some of them may surprise you.
Here are some other foods that can put a
dogs health in harms way:
Chocolate
Who can resist chocolate? Like it your not,
your dog. Chocolate is made with cocoa beans
and cocoa beans contain a chemical called
Theobromine, which is toxic to dogs. So on
Valentine's Day, you're actually being kind to
your best buddy if you eat all the chocolates
yourself! Read my special report on chocolate
at http://www.great-dog-gift.com/chocolate to
learn more, and see how different types of chocolate
have varying effects on dogs health.
Cocoa Mulch
Cocoa bean shells are a by-product of chocolate
production (which is how mulch made it into the
"foods" category) and are popular as mulch for
landscaping. Homeowners like the attractive color
and scent, and the fact that the mulch breaks down
into an organic fertilizer. However, some dogs like
to eat it and it contains Theobromine.
Fatty foods
Fatty foods are hard for a dog to digest and can
can overtax the pancreas, leading to pancreatitis.
This can threaten your dogs health and is potentially fatal.
Nuts
Macadamia nuts should be avoided. In fact most
nuts are not good for a dogs health since their
high phosporus content is said to lead to bladder stones.
Mulch
Mulch isn't food, but there's one type tempting
enough for dogs to eat. Some dogs are attracted
to cocoa mulch, and will eat it in varying quantities.
The coca bean shells can contain from 0.2% to
3% theobromine (the toxin ) as compaired to 1-4%
in unprocessed beans.
Onions
Onions, especially raw onions, have been shown
to trigger hemolytic anemia in dogs. (Stephen J
Ettinger, D.V.M and Edward C. Fieldman, D.V.M. 's
book: Textbook of Veterinary Internal Medicine
vol. 2 pg 1884.) Stay away from onion powder too.
Potatoes
Potato poisonings among people and dogs are rare
but have occurred. The toxin, solanine, is poorly
absorbed and is only found in green sprouts (these
occur in tubers exposed to sunlight) and green potato
skins. This explains why incidents seldom occur.
Note that cooked, mashed potatoes are fine for a
dogs health, actually quite nutritious and digestible.
Artificial Sweeteners
Xylitol is used as a sweetener in many products,
especially sugarless gum and candies. Ingesting
large amounts of products sweetened with xylitol
may cause a sudden drop in blood sugar in dogs,
resulting depression, loss of coordination, and
seizures. According to Dr. Eric K. Dunayer, a
consulting veterinarian in clinical toxicology for
the poison control center, "These signs can develop
quite rapidly, at times less than 30 minutes after
ingestion of the product" states Dr. Dunayer,
"...therefore, it is important that pet owners seek
veterinary treatment immediately."
Turkey
Turkey skin is currently thought to cause acute
pancreatis in dogs, partly due to it's high fat content.
Other foods listed by the ASPCA as harmful:
Alcoholic beverages
Avocado (the only "fatty" member of the vegetable family)
Coffee (all forms of coffee)
Moldy or spoiled foods
Salt
Yeast dough
Garlic
The Bottom Line
Thanks to a more educated public, fewer
fatalities from foods like chocolate are being
reported these days. But it's important to keep
up with what's currently known about foods
and their effects on dogs health. Grapes and
cocoa mulch, for example, were only discovered
very recently to have harmful effects. Check
frequently with sources like the ASPCA, or sign
up for the "Cold Noses News" and we'll keep
you informed. (You'll also get a bunch of cool
dog stuff along with your free registration).
Of course, being alert and getting your pet
to the vet promptly will help assure a happy
outcome if something unfortunate should
happen. Here's to your dogs health and good nutrition!
