There are also a number of non-food objects such as Pointsettias, Holly, and Mistletoe that are toxic to pets.
Christmas ornaments also pose a threat. Small pieces can be swallowed and either obstruct or puncture the digestive system. If you anticipate your tree being an issue opt for a small tree placed outside of your pets reach. Ornaments can be hung around windows or on strings from the ceiling.

Toys often contain very dangerous chemicals and toxins. HealthStuff has a great list of toys listed by toxicity level. You can search for toys you already own by name and brand, or do a search for low-level toxicity toys.
Our winters are often long and cold, making exercise an issue for a large majority of pets. An Interactive Toy or treat/food dispensing toy can be of some help, but of course nothing beats fresh air, so bundle yourself and Fido up for some outside fun. Interactive toys help maintain some level of physical activity and are also mentally stimulating. Some links can be found on Keystone Trainings Links page.
