Snowdrop is a Chihuahua with a loveable, confident nature and loves nothing more than sitting on knee and getting a fuss. She is available for adoption would settle well with another small dog.
Tulip is a black and tan Chihuahua and has a loveable nature, but can be a little shy when she first meets new people. She is also available for adoption with someone who will be able to spend plenty of time with her.
Chocolate and white Chihuahua Viola is also looking for a forever home. Having lived with a number of dogs previously, the RSPCA say she will settle better in a home where she is the only pet.
