Marley is 13 weeks now & growing like a weed. He is now 3 1/2lbs & his ears are slowly going up. They've very weird & "foldy"...so I'm not 100% convinced they'll be perky perky but we're still holding hope. LOL He is a spit fire of a thing though - reminds me a bit of the Marley we all know....just not as destructive thank goodness. Everyone is getting along great though. The two older boys can be a bit impatient on occasion & give a growl or show a bit of teeth when Marley is wanting to play & they're busy relaxing. No major problems though and otherwise they all play great -he really fits in perfectly!
