The student of the Faculty of Veterinary Medicine and Livestock, Sheila Irais Peña, developed and patented a non-invasive method of contraception with no negative effect on the breeds.

“This is at the experimental stage, our idea is to find a solution that is not harmful to dogs, or invasive like surgical sterilization, in addition, there are also other ways to sterilize dogs that can cause problems, “says Sheila Irais Peña, a student.

It should be noted that in December and January in Mexico, people usually donate puppies, and many of them end up being abandoned, which exacerbates the problem. This could be a very good solution.
