Up to $50 million in grants for research into nonsurgical sterilization methods has been committed by the foundation. A $25 million Michelson Prize has been offered for the first entity to develop a single-dose, permanent, nonsurgical sterilizing agent that is safe and effective in male and female cats and dogs.

Only during estrus will copulation result in pregnancy. During proestrus and estrus, females may have a clear, blood tinged, or bloody discharge. Dogs during these stages are often informally referred to as being in heat. The length of these cycles varies greatly among breeds and even between individuals of the same breed.
The pervasive spread of obstetric ultrasound technology around the world and the conflation of its use with creating a 'safe' pregnancy as well as the ability to see and determine features like the sex of the fetus affect the way in which pregnancy is experienced and conceptualised. [37]
Typical diagnostic ultrasound machines operate in the frequency range of 2-18 megahertz, whereas home ultrasound machines and therapeutic ultrasound machines operate in the frequency range of .7-3.3 megahertz. Diagnostic sonography is typically used to create an audio "image", such as during pregnancy to visualize the developing baby.
Diagnostic ultrasound studies of the fetus are generally considered to be safe during pregnancy. However, this diagnostic procedure should be performed only when there is a valid medical indication, and the lowest possible ultrasonic exposure setting should be used to gain the necessary diagnostic information under the "as low as reasonably ...

Essentially, ultrasound is considered safe. While other imaging modalities use radioactive dye or ionizing radiation, for example, ultrasound transducers send pulses of high frequency sound into the body and then listen for the echo. In summary, the primary risks associated with ultrasound would be the potential heating of tissue or cavitation ...
Treatment protocol also includes intravenous fluid therapy and/or administration of activated charcoal. [38] Large breeds are less susceptible to chocolate poisoning, but can still die after eating four ounces [39] of chocolate. Carob treats are often available as dog treats; these are unrelated to chocolate and are safe.
