Christmas Things That Aren't good For Your Dog

Christmas warning below for things dogs can get into which are big NO - NO's
My Christmas warnings - much of which should be given consideration year round:

remember Christmas presents under the that may have NO-NO's in the - I.E.  chocolates....

Yeast - bread dough  ( we did have a mighty drunk bunch of pigs one year from dough...)

Raw yeast
Raw yeast cells multiply too quickly for dogs’ gastrointestinal tracts. When dogs swallow unbaked dough, it can continue to rise, creating a risk of blockage or even rupture of the dog’s GI tract. In instances when a very large amount of yeast is eaten, the yeast also ferments inside the dog, producing alcohol, in which case alcohol poisoning can occur.  use your best judgement on when to involve the vet.
If you bake breads from scratch, or have yeast in your kitchen for any other reason, remember to keep it – rising dough in particular – in a safe, dog-proof location.

side note  2nd hand - vet fed ice chips while waiting for dough to pass naturally - cold to keep it from rising more in warm belly..

Chocolate
Pure baking chocolate is most toxic, while milk chocolate requires a higher quantity to cause harm. A 20-pound dog can be poisoned after consuming about two ounces of baking chocolate, but it would take nearly 20 ounces of milk chocolate to cause harm. Ingestion of cacao bean mulch can also be toxic.
Signs include excitement or hyperactivity, tremors, seizures, vomiting, diarrhea, abnormal heart rate/rhythm, drunken gait, hypothermia, and coma.
Non-toxic doses of chocolate may still cause some gastrointestinal upset due to the fat content and acidity.
If your dog has ingested a toxic dose, your vet may induce vomiting or pump the stomach (gastric lavage). Treatment usually includes the administration of activated charcoal and aggressive supportive care with fluid therapy and medications.

Tinsel and glass ornaments 
     just common sense here - things that break or can be swallowed

Common Holiday and Christmas Plants that are Dangerous to Dogs
Poinsettias are a mildly toxic plant and should certainly be used with caution, but the dangers are hardly ever serious or fatal. The milky white sap found in poinsettias contains chemicals similar to those in detergents and when large quantities are ingested, mild signs of vomiting, drooling, or sometimes diarrhea may be seen. Skin irritation can occur when in contact with the milky white sap as well. Due to the low level of toxicity seen with poinsettia ingestion, you are safe to use them in your house with caution.

    Peace lily           Calla lily             Lily of the Valley
In cats, Lilium and Hemerocallis genera lilies are the most dangerous. Eating even a small amount of the plant will have a severe impact on a cat's system, causing severe symptoms such as gastrointestinal issues, arrhythmia and convulsions.
Daffodils are also toxic to both dogs and cats. The bulbs are the most toxic; however, even a few bites of the flower can cause kidney failure and even death in cats.

Amaryllis (Belladonna)
The beauty of the flowering Amaryllis is only matched by its toxicity. The Amaryllis contains lycorine and other noxious substances, which is most concentrated in the bulb of the plant. This is the same toxin that is present in daffodil bulbs. symptoms include salivation, gastrointestinal abnormalities (vomiting, diarrhea, decreased appetite and abdominal pain), lethargy and tremors in both cats and dogs.
The bulb of the plant is reputed to be even more dangerous than the flowers and stalk.
Amaryllis contains a toxin called lycorine, Eating bulb tissue (or a very large amount of leaf or flower tissue) can cause stomach upset, nausea, vomiting, diarrhea, tremors, and convulsions.
The potentially harmful effects of Amaryllis are reflected in an alternate name for one species of the plant, which is belladonna lily. Belladonna is another name for the deadly nightshade plant, which is very poisonous.
The Amaryllis also goes by other names, including Belladonna, Saint Joseph Lily, Cape Belladonna and Naked Lady.

English Ivy
Handling English ivy can cause severe contact dermatitis, or skin inflammation, which may be accompanied by blisters. This is the most dangerous aspect of the plant for most people.
Ivy is poisonous when taken internally, although a large amount of plant material needs to be eaten to cause symptoms. These symptoms can be serious and include a burning sensation in the digestive tract, breathing difficulty, gastrointestinal problems, delirium, hallucinations, and seizures.

Yew
Yew contains chemicals called taxines which quickly cause an irregular heartbeat after being eaten. The alteration in the heart rate can be life-threatening. Yew poisoning can also cause a headache, dizziness, gastrointestinal problems, breathing difficulties, trembling, convulsions, dilated pupils, and a coma.

Coleus
Coleus is non-toxic to humans but is toxic to pets. It can cause vomiting and diarrhea in dogs and cats, which may occasionally be bloody. In a home without pets, however, coleus is a beautiful plant to display indoors at Christmas and during the rest of the year either indoors or outdoors.

Cyclamen
Cyclamen poisoning may cause severe vomiting and diarrhea accompanied by significant fluid loss from the body. It may also cause heart rhythm abnormalities and seizures. The Department of Horticultural Science at North Carolina State University considers cyclamen to be "toxic only if large quantities eaten".  the bulb is the part of concern and is bitter, thus between being buried in soil and tasting bad may be less of a concern but worthy of mentioning since some dogs get into anything.  not that any if mine would ever do that.... yea... right............

Christmas rose
The Christmas rose or Helleborus niger,  is another poisonous plant whose toxicity depends on the amount that's eaten. Eating the plant can result in a burning sensation in the mouth and throat, abdominal cramps, nausea, vomiting, diarrhea, weakness, depression, and a slow heartbeat.

Jerusalem cherry
The plant is also known as the winter cherry and the Christmas cherry.
The fruits of the Jerusalem cherry are sometimes confused with cherry tomatoes. This is a serious mistake, since Solanum pseudocapsicum is poisonous. The plant contains a toxin called solanocapsine. The leaves and unripe fruit contain the highest concentration of the toxin.
The assessments of the Jerusalem cherry's danger vary widely and range all the way from "mildly poisonous" to "deadly". It seems like a good idea for families with young children or pets to avoid this plant and err on the side of safety. Symptoms of poisoning include headache, stomach pain, vomiting, diarrhea, drowsiness, and slow breathing.

    Autumn Crocus
The Autumn Crocus, also known as the Meadow Saffron
The Autumn Crocus (Colchicum autumnale) is a flower that physically resembles a true Crocus plant, but is actually a lily. Like other lilies in the Colchicum family, it contains a poison called colchicine for which there is no known antidote. Ingestion of this plant, also known as the Meadow Saffron or naked lady, can cause severe gastrointestinal distress, damage to multiple internal organs, and without treatment will usually lead to death.

   
    Holly – the berry and leaf            Mistletoe
Mistletoe contains multiple substances that are toxic to both dogs and cats, including toxalbumin and pharatoxin viscumin (lectins, phoratoxins). It’s well-known for causing severe intestinal upset as well as a sudden and severe drop in blood pressure, breathing problems and even hallucinations (showing up as unusual behavior).
If a large enough amount of these plants are ingested, seizures and death may follow.
The leaves and berries of holly and mistletoe plants, even the dried plants, should be kept well out of your pet's reach, or better yet, kept out of the home altogether.

The Christmas Tree itself
There are dangers beyond lights and ornaments.
Firs, spruce, pine trees, and cedars are the trees that are most often used as Christmas trees and as greenery for decorations.
The oils produced by fir trees can be irritating to a pet's mouth and stomach. The tree needles, meanwhile, may cause gastrointestinal irritation, obstruction and punctures.
the water used for Christmas trees can be noxious. Bacteria, molds and fertilizers can cause your pet to become extremely sick with only a few laps of water. Keep the water covered and blocked off to prevent pets from accessing it.

Sago palm
 All Cycad plants, including sago palm, are extremely poisonous.
Although many pets may find cycad plants very palatable and pleasing to chew on, all parts of this plant are highly toxic: leaves, trunk, roots, and seeds. The newly sprouting leaves and the reddish seeds are particularly poisonous. Ingesting even one seed can kill a dog.
The primary toxic agent of the sago palm and other cycads is called cycasin. It is both a neurotoxic glycoside (a nerve-poisoning plant sugar) and a carcinogen. The mortality rate of pets that have ingested Sago plant is high - up to 75%.

Dieffenbachia
(Dumb Cane) -- aka; palm lily, cornstalk plant, corn plant, ribbon plant, dragon tree, Madagascar dragon tree, money tree, lucky bamboo With its broad variegated leaves, the dieffenbachia is often recommended as an ideal houseplant for natural air purification.
But if you choose to have one in your home, be sure it's well out of your dog's reach. When eaten, it not only burns the mouth and throat but causes the esophagus to swell, potentially blocking the dog's airway.
