A mechanised four legged nostalgic animal that a Mum with kids might buy?

I wake up. Lee has already got out of bed and is upstairs. I go to walk upstairs, as soon as my foot reaches the bottom step, the stairs creak. I hear Lee rush to the living room door upstairs and appear at the top of the staircase.
"You can't come up!"
"What, why?"
"You just can't!"
"Why?"
"I'm looking at porn!"
"No you're not. Are you shopping for a Birthday present?"
"Maybe!"

Six hours later.

"I can't keep it a secret anymore. Do you want to know what it is?"
"Erm. No, my Birthday isn't for over a month."
"But I can't keep a secret anymore!"
"I want to wait."
"Do you want a clue?"
"No"
"Okay, well it's something a Mum with kids might buy."
"Right...?"
"Do you want another clue?"
"No"
"Well it's something nostalgic."
"Okay"
"Do you want another clue?"
"No"
"Well it's something to do with a four legged animal."
"What?"
"And it's a machine."
"So a mechanised four legged nostalgic animal that a Mum with kids might buy?"
"No!"

Can you figure out what it is?

Well. I leave the room, I come back five minutes later. As I open the door and walk in Lee shouts. "No don't come in!" I see a blender on the screen.

"You got me a blender?"
"No, it's a slushy machine."
"Cool, we can make alcoholic slushies... but... how is that anything to do with a four legged animal?"
"Slush PUPPY!"
"I see."
"Don't worry i'll get you another suprise for your Birthday."
"Okay... but please don't give it away this time."
"I won't. I'll buy you two gifts for every gift I accidently tell you."

Safe to say I'm going to have thousands of gifts by my Birthday... Hooray!
