IAN CULL EXPLAINS HOW YOU CAN HELP AND THE CHALLENGES SHELTERS ARE FACING. >> Reporter: ANIMAL SHELTERS ACROSS THE BAY AREA ARE BURSTING AT THE SEAMS. WE SPOKE WITH TWO SAYING THE SPIKE IN BIG DOGS, ON TOP OF THAT, KITTEN SEASON. >> WE'RE GETTING LITTERS IN NEED OF HELP. >> Reporter: TARA DAVIS IS A SUPERVISOR AT THE SAN JOSE ANIMAL CARE CENTER. SHE AND OTHER EMPLOYEES HAVE BEEN FOSTERING PETS AT HOME TO TRY AND HELP RELIEVE OVERCROWDING. NOW THE SHELTER IS WAIVING ALL ADOPTION FEES THROUGH THE END OF NEXT MONTH TO TRY AND GET MORE ANIMALS ADOPTED. >> WE HAVE ABOUT 814 ANIMALS CURRENTLY IN CARE IN THE SHELTER. OUR CAPACITY IS LESS THAN HALF OF THAT, HONESTLY. WE'RE WAY OVER CAPACITY. >> Reporter: THE SITUATION IS JUST AS DIRE IN OAKLAND. ANIMAL SERVICES DIRECTOR ANN DUNN WROTE IN A HEARTFELT POST, THEY HAVE COME CLOSE TO HAVING TO EUTHANIZE SOME BIG DOGS OVER THE PAST SEVERAL MONTHS DUE TO OVERCROWDING. NOW THEY SAY IT MAY BE UNAVOIDABLE. THEY'RE POSTING DOGS AT THE GREATEST RISK OF BEING PUT DOWN ALONG WITH THE DEADLINE DATES TO ADOPT THEM. >> WHAT WE'RE TRYING TO DO IS BE COMPLETELY TRANSPARENT. THE ONLY WAY THAT DOGS CAN LEAVE THE SHELTER ALIVE IS IF THEY'RE ADOPTED OR A TRANSFER PARTNER, A RESCUE ORGANIZATION, HELPS THEM. SO WE REALLY HAVE TO RELY ON THE COMMUNITY. >> Reporter: ANN DUNN SAYS THE LOCAL HOUSING CRISIS IS ONLY MAKING THINGS WORSE. >> THE ISSUE IS, THERE'S AN EXTREME SHORTAGE OF AFFORDABLE HOUSING THAT ALLOWS PETS.
