Meet Eddy — a dog who knows exactly when his family needs a little extra help.

Ashley Karlin adopted Eddy, a black Lab, from a shelter two years ago as a companion for her senior dog, Daisy. And since that day, Eddy and Daisy have been inseparable.

“Eddy and Daisy play like siblings. They egg each other on and run around in the backyard together,” Karlin told The Dodo. “They sleep next to each other and sometimes on each other.”

The 95-pound cuddle bug is also extremely perceptive. Eddy can sense immediately when something is off with a member of his family — and he hops into action.

Eddy uses this skill frequently when traveling with his sister. Daisy has always had car sickness and gets anxious when it’s time to go for a drive, but Eddy is a pro when it comes to soothing her.

“When she lies down in the back seat and starts to drool, Eddy lays the opposite way so he can rest his head on top of hers,” Karlin said. “If he doesn’t do this, Daisy constantly gets up, lies down, gets up, lies down on repeat until she vomits.”

“I think Eddy just has a sense of when others aren’t feeling well and he’s always there to comfort her,” Karlin added. “We’ve noticed every time they lie down together like this, she doesn’t puke and usually will fall asleep.”

Eddy also monitors his mom to make sure she’s OK and is always the first to know when there’s any change.

“My husband and I recently found out I’m pregnant, and one of the signs that tipped us off was that Eddy constantly would put his head on my tummy,” Karlin said. “Eddy has [also] on numerous occasions woken me while sleeping to alert me that I was going hypoglycemic, even though he’s not trained to do so.”

Eddy is always there when his mom or sister needs him — and they can’t picture their lives, or car rides, without him.
