Pup Visiting Grandma - ok for a week?

[Ling]

Morning all,

My boyfriend wants a break from our little pup and wants to leave her with his mom for a week. We've had her for about 3-1/2 months now and I haven't been away from her for more than 4 or 5 hours at any time - I think 2 times since we've had her... She pretty much comes any and everywhere with me except when I'm grocery shopping or the rare occasion that I go out. She even comes to work with me too - which I love! (In her house behind me quietly chewing her bone now :-)
His mom has a big back yard, 3 dogs for her to romp and play with and is taking a week off - so I'm not worried that she'll be alone or bored. What I'm worried about is that she'll feel like I've / we've abandoned her and / or get confused over where her home is and who is her family.
Am I just being a crazy overprotective mom? Just selfish and worried that I'll miss her too much?
If it were my choice I wouldn't leave her at all, but he says that we need some alone time. And yes - I think I pay more attention to her than him... I was thinking more like a couple of days. Would that be ok?

Please let me know what you all think. Thanks!
