Playful Ridgeback cross Buster only has three legs and is desperate to be rehomed after an animal centre reached its full capacity.
An RSPCA shelter saw an "unprecedented" influx of animals in the last month and is urgently trying to rehome pets.
A spokeswoman for the animal charity said the RSPCA Blackberry Farm Animal Centre, near Aylesbury in Buckinghamshire, took 178 animals into care in September.
Among the 30 dogs in the kennels is eight-year-old Buster who - despite only having three legs - needs a lot of exercise.
The spokeswoman said the playful and lively dog needs to be adopted by an experienced owner.
Centre manager Julie Allen said the situation is "heart-breaking".
Ms Allen said: "We just cannot stress enough how dire the situation currently is. More and more people are just dumping their animals, without any remorse or care.
"Sadly the fact is we are getting more animals coming in than are going out and being rehomed.
"It is depressing and heartbreaking, we can care and nurture these animals - but what they desperately need is a good kind owner to look after them."
