After discovering Christmas pudding was absolutely not for dogs in a Dogs Today article earlier this year, are there any other foods I should avoid feeding my dog this holiday season?
Christmas food
hazards are:
Chocolate
Chocolate
contains theobromine, a chemical very similar to caffeine, which dogs do not
tolerate very well. The amount of theobromine depends on the quality and type
of chocolate. White chocolate contains very little and is generally not a risk
but even a relatively small amount of dark chocolate (which is very high in
theobromine) can cause agitation, hyperexcitability, tremors, convulsions and
problems with the heart. Dogs will
not unwrap chocolate and can eat a very large quantity. The wrappers are not
toxic but could cause obstruction of the gut. If there are dogs in the
household or are visiting over Christmas do not put any chocolate under or on
the Christmas tree.
Onions (and
garlic, leeks, shallots and chives)
Onions, garlic,
leeks, shallots and chives all belong to the Allium species of plants. They can cause toxicity even when
cooked. Initially there can be gastrointestinal signs with vomiting and
diarrhoea but the main effect is damage to red blood cells resulting in
anaemia.This may not be apparent for several days after ingestion. Foods to avoid at Christmas include
sage and onion stuffing.
Grapes and
dried fruits (currants, sultanas, raisins)
Grapes and
their dried products (currants, sultanas and raisins) are toxic to dogs. Ingestion of even a small
quantity can cause severe kidney failure. Don’t forget this will include food
items that contain dried fruits such as Christmas pudding, Christmas cake and
mince pies. Be aware that chocolate-coated raisins are available so there is
the additional risk of chocolate toxicity with these.
Xylitol (food
additive code E967)
Xylitol is a
naturally occurring, sugar-free sweetener and is frequently found in sugar-free
chewing gums and sweets, and some pharmaceuticals including nicotine
replacement chewing gums. Xylitol is extremely harmful to dogs and can cause
low blood sugar (hypoglycaemia) and liver damage.
Alcohol
Dogs may help
themselves to any alcohol left unattended including wine and liqueurs and it
can cause similar signs in them as it does in their owners when drunk in
excess. Dogs can become
wobbly and drowsy and in severe cases there is a risk of low body temperature,
low blood sugar and coma.
Bread dough
Uncooked bread
dough that has been left to prove can be hazardous to dogs. The dough expands
in the warm, moist stomach and this can result in bloating and obstruction. Also
the yeast produces alcohol and this can cause additional effects (see above).
Macadamia nuts
Macadamia nuts
can cause lethargy, increased body temperature, tremor, lameness and stiffness.
Be aware that chocolate-coated macadamia nuts are available so there is also a
risk of chocolate toxicity with these.
Leftovers
If there is any
food left over at Christmas, be careful to dispose of it promptly and
appropriately. Mouldy food (including yoghurt, bread and cheese)
can contain toxins produced by the mould that cause rapid onset convulsions in dogs.
**Ed’s note – the toxicity mechanism regarding
grapes/raisins and dogs is not fully understood by scientists. This means any
amount could be fatal to a dog of any size. The advice from the world’s top
scientists is NOT to give you dog any grapes, raisins, sultanas, or any
products containing them such as Christmas cake, pudding, and/or mince pies.
Even if dogs have been fine eating these products before, because the science
is not understood, it is not safe to say that these dogs will be ok with the
next grape they eat. Please avoid these foods to avoid tragedy this Christmas.
