Okay, so we've bought the new girl home (on Sunday) and Roxy's gone nuts. I'm not sure if she's actually fighting with Tia or just playing but she seems kinda rough and does make Tia yelp every so often. There's lots of tail wagging going on and Tia doesn't seem to be worried when Roxy charges for her, she even follows behind until she gets some attention. I'm just a lil worried that Roxy will hurt Tia, I can't imagine that being bounced on and mouthed constantly is great for her. Roxy's just coming up for 5 months and Tia's only 8 weeks old. Should I be keeping them apart more or am I just worrying for nothing? Advice please

Oh, and I'll post pictures soon, when I can get Tia to sit still lol
