Two animal welfare groups are petitioning the authorities to ease size restrictions for adoptions under a programme to house mixed-breed dogs in Housing Board flats.
Action for Singapore Dogs (ASD) and Save Our Street Dogs (SOSD) have asked the Ministry of National Development (MND) to revise the criteria for Project Adore.
Under the current scheme, only mongrels up to 50cm in height and 15kg in weight are allowed to be kept in HDB flats. The groups want the limit raised to 60cm and 20kg, to allow more dogs to qualify for adoption by HDB flat owners.
ASD president Ricky Yeo said: "The current parameters limit the number of dogs that may have the right temperament, but are unable to be adopted because they are a little bigger."
Ms Kieran Kua, a full-time shelter officer at SOSD, said the current limit means only about 20 per cent of their estimated 140 dogs can be adopted through Project Adore.
Raising the limit expands the number to about 60 per cent of the dogs they have, she said.
When contacted, a spokesman for MND said it is reviewing the request. She added: "Any policy adjustments have to be done sensitively."
The MND also hopes to expand the scheme by roping in more animal welfare groups, on a case-by-case basis, the spokesman said.
Project Adore was first mooted by the Society for the Prevention of Cruelty to Animals (SPCA) and ASD in 2011. The MND started a pilot scheme in 2012, which was made permanent on May 28 last year.
SOSD joined in May last year.
