Strong winds blew away the tarps over the dogs' cages, while the flooded country roads in the area made it difficult for volunteers from the Haver and Let The Animals Live organizations to get to the shelter and extract the dogs from there.
On Friday morning, eight puppies were rescued after they sank into mud and taken for medical treatment.
The Netanya municipality worked to find the dogs somewhere to stay during the weekend, with Veterinary Services personnel sent to Kibbutz Yakum to assist.
"We must find foster homes for the 50 dogs in Yakum," said Eti Altman, the founder of Let The Animals Live. "As a result of the weather, there is no dry shelter for the dogs. They've been running around for hours drenched in water and shivering from the cold."
Altman called on the public to help find a place for the dogs to stay, warning, "The smaller dogs won't survive the night in this cold."
Rachel Salit, the head of the Haver organization, also asked for help. "Please reach out and help the dogs to prove man is also dog's best friend. Dozens of dogs remain in the shelter, and it'll take us time to reconstruct the covered areas," she said.
"We're making every effort to rescue the dogs, and I hope on Saturday it will already be possible to come and take the dogs and adopt them or provide them with a foster home."
