Is dog litter organic or inorganic

Dog poop

Bag dispenser with garbage can

Dog poop is the mostly solid excrement (excrement) of the intestines of dogs. Since dogs usually pay for the droppings when they run outdoors, the question arises for society as to how to deal with it and how to dispose of it.

In Germany, the regulation of dog ownership is a matter for the municipalities. Usually, the municipalities oblige the dog owners to clean up the remains of their animal themselves. Anyone who does not do this is committing an administrative offense that can be punished with a fine. In some cities, bag dispensers are set up to remove dog waste.

Exceptions often apply to guide dogs for the blind, dogs in use by security organs and the like.

Danger from dog feces

Dog feces represent a risk of accidents for people with limited mobility. Blind, visually impaired and wheelchair users often cannot avoid the dog poo and thus come into direct skin contact with the feces. Guide dogs guide their owner safely around the legacies of their conspecifics and are trained to relieve themselves in places where normally nobody would go.[1]

Dog feces represent a potential risk of infection, with children and adults with a weakened immune system being particularly at risk. Numerous tiny parasite eggs can be spread far into homes through shoe soles, for example. There is therefore always the risk of indirect contact with dog excrement, for example via contaminated play sand. Other dogs can become infected by sniffing faeces. Roundworms, whipworms, hookworms, tapeworms, fox tapeworm, giardia and coccidia are named as dog feces parasites. Since deworming is not carried out regularly, one in three dogs can be expected to be carriers of intestinal worms. Symptoms for this usually remain unremarkable in adult animals. [2]

In a dispute, the Düsseldorf District Court ruled: "Anyone who excretes a dog on a playground and lawn and does not remove the manure is liable to prosecution for environmentally hazardous waste disposal." (AG Düsseldorf, judgment of August 11, 1989 - 301 OWi / 911) . It justified that the contamination of the playground with dog excrement posed a risk of infection of playing children with the pathogens of publicly dangerous and communicable diseases.

Due to the increased spread of the fox tapeworm in the moderate climatic zones of Central Europe in recent years, the feces of a dog infected by the fox tapeworm can also pose a threat to humans. The dry animal excrement can be inhaled unnoticed and with it the tapeworm eggs in it. In Germany, an average of 17 cases of reportable alveolar echinococcosis are registered each year.[3] The dog tapeworm, which is partly contained in dog excrement, represents a further source of danger for humans. Here, humans act as intermediate hosts. Once infected, a person can become critically ill. The probability of infection is considered low in each case.

Dog poop can be dangerous to agriculture if it contaminates pasture land. Are there Neospora parasites (Neospora caninum), they stick to the grass for a long time. If these contaminated grasses are eaten by the cows, this can lead to stillbirths. However, a study by the Friedrich Loeffler Institute (Federal Research Institute for Animal Health) shows that this risk of transmission can be classified as extremely low.[4] In addition, dogs themselves must be infected with Neospora caninum in order to be a source of danger.[5] City dogs are therefore, according to the state office, "Generally excluded from this infection process". If the remaining dog excrement ends up in the haymaking, a large part of this winter feed is refused by the cows.

National regulations

No dog waste sign in Japan: "Please don't let [your] pet [here] make a pile."

In Germany, dog owners are usually obliged to remove dog excrement within the framework of municipal regulations. In some parks and green areas where dogs are allowed, dispensers with bags to collect the droppings are set up.

The Austria regulates § 92 Abs. 2 of the road traffic regulations: The owners or keepers of dogs must ensure that they do not contaminate sidewalks and sidewalks, as well as pedestrian zones and residential streets. This also applies in dog zones.

In Switzerland, there is an obligation in many municipalities to collect dog waste and dispose of it in a specially designated waste container (Robidog). Violators face penalties. For this reason, leash is generally required in the canton of Schwyz.

Also in Switzerland there was even a popular initiative in the 1980s that wanted to make the use of dog toilets mandatory in the constitution. However, it did not get the necessary number of signatures for a referendum.[6]

In Liechtenstein there is also a legal obligation to remove dog excrement. For this purpose, waste bins have been set up throughout the country (not only in populated areas, but also on hiking trails).

Use of dog poop

Dog poop was previously used in the manufacture of certain types of leather. Soft leather was stained with dog droppings before tanning. This opens up the skin further and breaks down protein that is not part of the leather structure. The procedure has also been used to depilate the skin.[7]

This process fell into disuse after Robert Hasenclever began producing the enzyme pancreatin on an industrial scale between 1895 and 1897. It was used in the tannery by Otto Röhm in 1907.[8][9] The effect of the dog's excrement is not achieved by the excrement itself, but by bacteria that settle on it, which release the enzyme trypsin.[10] The dog feces were collected for this purpose on a commercial basis.

Under the name of excrementum caninum, abbreviated excr. can., dog excrement is used as a remedy in homeopathy.
