Fostering is temporarily opening your home to a homeless pet to provide relief from the shelter and open space at our facilities. Fostering can be long or short-term, for medical/age reasons, for transport prep, or just to give one of our dogs or cats a break.




How does fostering help? 

The shelter environment can be stressful for animals. It can be loud, they don't know where they are or why, and they have no control. This stress can lower an animals immunity, cause abnormal behavior, and affect an animals overall health. Fostering helps give animals a break from the shelter environment and learn what it's like to be in a home.

Kitten Season is Coming! 

Kitten season is quickly approaching, and we need all hands on deck! Just last year over 1,000 orphaned kittens went through our foster program, and we are preparing to care for a similar volume of un-weaned kittens this year. If you're able to open up your home to an orphaned kitten but aren't sure where to start, check out this informative course on how to care for those particular pets. If you're unable to foster, please consider donating items on our Amazon wish list to ensure that our fosters can care for our most vulnerable population.

Fostering a Dog with Distemper

What is Canine Distemper Virus?

Canine Distemper Virus (CDV) is a viral infection that affects primarily dogs.  It causes upper respiratory signs (cough, nasal discharge, eye discharge), gastrointestinal signs (decreased appetite, vomiting, diarrhea), and occasionally neurological signs (seizures, tremors, stumbling/difficulty walking).  In severe cases, CDV infection can be fatal, although many dogs have only mild signs (or no signs at all). 

Is it safe for my family to foster a distemper positive dog? What if I have other pets in the home?  Isn’t this a serious contagious disease?

  • Adult, fully vaccinated dogs are protected against this disease - our vaccine for distemper is extremely effective.  Vaccinated adult dogs can be around a positive dog and, if their vaccines were effective, will not be at risk of becoming ill.

  • If you either do not have dogs at home or have only adult, vaccinated, otherwise healthy dogs, you can safely foster a distemper positive dog. 

  • Some dogs that test positive for distemper don’t even have the virus - a positive test can also be related to vaccination.  Our test cannot distinguish, though, so we house them cautiously so as not to spread the virus to vulnerable dogs.

  • You cannot safely foster if you have puppies (even vaccinated ones) or adult dogs that aren’t vaccinated or have an  immune system compromise. 

  • Cats and humans cannot get distemper virus; ferrets and some wildlife can.  Do not foster a distemper dog if you have pet ferrets.

Key points for foster families:

  • Even though a dog appears clinically healthy, they can be shedding distemper virus for up to 4 months (occasionally longer) after infection – this means they are potentially contagious to other at-risk dogs for this period of time.

  • Viruses can live in the environment, on objects, or on *you* and can then be transmitted to other dogs for several hours.  

  • Distemper affects primarily dogs, but it can also affect ferrets (usually fatal) and other wildlife. It does not affect humans or cats.


Our organization relies on community support to do the lifesaving work we do. Be a part of this work and donate today! Your donation will allow us to grow our programs and help more animals across the RGV.
