And you're the one who called them wood CHIPS not shavings but IRregardless they should have some old army blankets out there. Now get your ass in the car & go to Big Lots or K Mart and splurge $4.00 each on some fleece throws. Poor dogs.
The Problem with Cedar and Pine Shavings as Pet Bedding and Litter
Cedar and pine shavings are commonly available pet bedding products - but are they
harmful to the very animals for which they are intended?
Cedar and pine became popular for pet bedding material because they are good at
controlling odor and have some natural insecticidal properties (they kill or repel bugs,
especially cedar). These softwood shavings smell nice due to the volatile compounds
(e.g. aromatic hydrocarbons, phenols) that are given off. Unfortunately these
compounds have been implicated as a potential health risk, especially with regards to
respiratory problems (asthma, inflammation, allergic responses) and changes in the
liver.
Many of the studies on wood toxicity have actually been conducted on humans, who
are exposed to these woods and their by products in the wood product industry (such
as those who work in lumber mills who are exposed to lots of wood dust), and these
studies often compare the incidence of disease in workers in the wood product industry
compared to other workers or the average population.
Studies of laboratory animals have shown fairly dramatic changes in liver enzymes on
animals housed on cedar bedding. This in turn can effect the metabolism of drugs
including anesthetics, but a direct link between these changes and disease or clinical
symptoms hasn't been as clear.
However, based on the studies that implicate the compounds in allergic and respiratory
diseases as well as the impact on liver enzymes, it seems prudent to avoid cedar
shavings as bedding or litter, especially since alternatives are available.
With pine shavings, the problem isn't quite as clear cut. Pine shavings emit similar
volatile compounds but the risks aren't as clear. Many say that drying the shavings
releases most of the volatile compounds, so that products such as kiln dried pine are
safe.
