I’m sorry to hear that a pet was dumped and had flipper toes which made them difficult to be bought. It’s always heartbreaking to hear about animals being mistreated or abandoned.
If you are in a position to help, you could consider contacting your local animal shelter or rescue organization to see if they can take in the pet and provide them with the care they need. They may be able to work with a veterinarian to provide any necessary medical treatment and find the pet a loving home with someone who is willing to care for them despite their unique physical condition.
If you are unable to take in the pet yourself or find an organization to help, you could consider spreading the word on social media or with friends and family to see if anyone knows of someone who is willing to take in a pet with special needs. Every little bit of effort can help make a difference in the life of an animal in need.
