Contraceptives for street dogs in Mexico City

Mexico City is facing a huge problem with street dogs that roam the city. Reasons for this zoological epidemic that allows proliferation and contagion of all type of viral, infectious, respiratory and gastrointestinal diseases are numerous – scarcity of homes, lack of females, abandoning, and so on.

Alex Lora was right when he said: “nobody cares about my future, it is written that I have to suffer.”
It seems that Mexico is a host of the main urban safari. It is on the top of the list of Latin American nations with more lost or abandoned dogs: more than 23 million. Records claim that 70% of the dogs in Mexico City (CDMX) were abandoned by their owners and according to figures to the Mexican Association of Veterinarians Specialists in Small Species this population increases 20 percent each year.

Sheila Irais Peña, Ph.D. student at the National Autonomous University of Mexico came up with a solution for this invasive issue: contraceptive croquettes to reduce (and at some point cease) the reproduction of the street dogs. She is currently working on a “natural product”, composed of sex hormones such as progestins and androgens that works for the control of reproduction.

Another student of the Faculty of Veterinary Medicine and Animal Science explained for “Vanguardia” that the main objective is to develop a contraceptive method that would not be not invasive and nor would have negative effects for the races.

Street dogs became a threat for the city. An issue that has to be solved somehow since there is not enough space to accommodate them. The problem does not stop there. They also imply a health problem since every day a homeless dog defecates 400 grams and urine 800 milliliters: almost half a ton of waste per day, 182 tons per year.
