It reminds me of my first visit to the vet with Topher....I'd only had him less than 24 hours...he was 18 wks old and around 7 lbs (to me he was TINY compared to the terrier mix I'd lost in January who was 40lbs!!)...my vet's first words were 'OMG, he's HUGE!! I was shocked..."huge??" He was so tiny to me!! (she did say it lovingly, but I still was surprised!)
Next was my trip to the groomer a couple of weeks later..."OMG, he's huge!!" from one of the girls who works there....
He's 8 lbs now at 6 mos. and to me he's still so tiny sometimes!! I just LOVE his little butt when it waggs (and the tail, too

) He's my baby and I wouldn't have him any other way!!
