"They're all out there getting pregnant right now," said Roman.
Some of the animals are lucky enough to be found, rescued and treated, like Tigger in West Palm Beach.
"He had a completely shattered leg and one dislocated hip," said Amber Marzo who adopted the dog two months ago. Volunteer Mirta Maltes, of Chain of Love Abandoned Dogs Everglades, found him and rescued him.
You wouldn't know it by looking at him run, but Tigger was hit by a car and found along the side of the road and needed major surgery.
"I don't have kids, I treat him like a child so I don't understand how people could treat animals like that," said Marzo.
However, there's only a handful of volunteers who patrol the streets looking for animals when they can.
"Why are people dumping them, instead of taking them to a shelter where they could get help?" asked Contact 5 Investigator Dan Krauth. "I don't know, it would be better to take them to a police or fire station, like you would a baby," said Maltes of Chain of Love Abandoned Dogs Everglades.
The volunteers don't have enough space or money to house all of the animals they find. Many of the animals they discover need medical treatment.
"You can stop and feed them but I can't take them all," said Maltes.
"How can a rational mind with a heart in their body make sense of dumping a helpless animal in the middle of here, nowhere, in the Everglades to just starve and suffer, how can you make sense of something like this?" asked Roman.
When there's a spike in foreclosures, volunteers said they see a spike in the amount of dogs running the streets.
Together both groups have rescued more than 1500 animals over the past three years.
