Our natural ecosystem can handle 2 dogs per square mile. In urban areas, there can be as many as 125 dogs per square mile. Yes, wild animals poop, but our environment is not equipped to process the added waste from the millions of pets we share our lives with.
Dog waste can take a year or more to fully break down, depending on climate, the dog's diet, and other factors. The chances of the waste decomposing and being absorbed by your lawn or other plants before rain water washes it into the nearest stream, creek, or river are slim. Even if it does decompose, the bacteria and parasites can linger in soil for several more years.
Dog waste can be composted as long as the temperature of the compost pile becomes hot enough to kill any parasites. Generally, you should not add dog waste to regular compost bins or piles. There are composters on the market that are specially designed to handle dog waste. It is not recommended that you use dog waste compost in food gardens unless you are absolutely sure that any parasites and bacteria have been killed.
Cat waste should never be composted due to the risk of toxoplasmosis.
Do not put any pet waste in municipal compost piles unless you are specifically directed to do so.
Every dog (as well as every human and every other warm-blooded animal) carries fecal coliform bacteria, which can become a health hazard in waterways, as well as an environmental contaminant.
Perhaps not worse, but single use plastics certainly have their own drawbacks.
You can opt for biodegradable bags, which are usually made from vegetable resins or maize flour. However, even biodegradable bags may not completely break down in a landfill, due to the lack of oxygen. They will, however, decompose in a dog-waste-only composting bin.
A great alternative to bags is newspaper. Newspaper naturally decomposes, and you're reusing something you would have thrown away (or recycled) anyway.
No. Our wastewater system is not designed to handle animal waste.
If your home has a septic tank, it is best not to flush unless the installer and manufacturer verify that the system can handle it.
