Transcript for Snooze or Study Right Before an Exam?
me ??? Thank you. Thank you. Thank you. That's beautiful. ??? Oh, man. Little knee socks. Really getting into it. People that are going through their something to have that kind of love and support means everything so it just gives us an example what we all can do to help one another. That was fun. Thank you, robin. Feel Good Friday. Want to feel good again? Oh, yes. We all love dogs. Did you see the difference it made in all of our moods yesterday. Our statistics, we like to do it regularly. Come to mean so much to us, this mission that we're on to get dogs adopted and call it mission pawsible because we love a pun but we are serious about it and want to reveal to you now our new number. Very, very proud of this. Our forever homes are now adding up to, drum roll, please. 3,702 dogs. Those are some of the pictures there. But you know there's one group of dogs that it's not quite as easy to find hopes for. Those are the senior dog, dogs that hit three years old, all of a sudden their chances of finding a home go down dramatically and we want to try to change that perception and change your mind on that. Take a look. ??? these three are part of my family. Everybody, meet cocoa, age, 5 or 6, Harry, maybe 13 and dandy, timeless. All rescued when they were full grown. No puppies for me. I actually like the idea of giving a second chance to adult dogs who wouldn't need all the training a puppy requires. You want to go for a walk? Give me a hug. My new friend and fellow dog lo lover Erin Stanton couldn't agree more. She owns two already and has become a champion advocate for older dog adoption. The staggering statistic when dogs hit 3 years old their adoption chances really plummet. They only get better with age. It was her 17-year-old rescue Susie that inspired her to create Susie's senior dogs, a nonprofit and social media sensation with more than 500,000 followers and posts profiles of elder DI dogs in need of loving homes. Are you ready? Christie who spotted 10-year-old bourquet on her Instagram but was initially skeptical. He had almost no hair and it was all wiry and he weighed seven pounds and now he weighs 13 pounds. Reporter: Once a New York City stray, this little guy now has a new leash on life. He has a total love for life. He loves to play. He loves to roughhouse. He's not geriatric. How does that feel to know that you have rescued 700 dogs? Well, the easy part in my opinion is writing about them but the day that they go home, it's the adopters, 700 people who opened up their heart to a senior dog. Er compiled her favorite success stories in "Susie's senior dogs" where she highlights human dog matches and advocates for elderly dog adoption. Think people are worried about medical. The thing, you know that I always say, just like humans, not all old dogs have medical issues. Another myth is that they're not going to bond to your family because they're already formed. I in fact think an older dog is more grateful. Somehow innately though know. Through it all both Erin and I have the same message when looking to adopt keep an open mind. Keep an open mind. That's all we ask. We have two senior dogs here from the humane society of new York. They could really use some homes full time. They are wonderful, wonderful dogs. So much love to give. Housebroken. They're done. They're ready. All they need is you and you can check the humane society of new York City and any of our participating shelters across the country on our website, goodmorningamerica.com. Very curious. Yes. I just want to say sort of like dating. Have an open mind. Don't judge a book by its cover. Just like dating. It is. Just like dating. You never know. So and a dog like this little Mitzi and Perry, they could live to 18 or 19 years old so don't think, oh, I don't want to get attached and then I'll be sad. They have many years of love to give so I know I'm begging. I am begging so just please consider adult dogs.
