Detox, I can't comment on the puppy part since all of my dogs have been over a year when I got them, but about the doggie daycare. If they are willing to take your dog in at 8 weeks, RUN the other way. That sort of environment has the potential to be very hazerdous to your pup's health. I work at a boarding/daycare resort and we do not allow in any dogs under 16 weeks (4 months). They MUST have all their puppy shots before being allowed in...this is for THEIR safety. Otherwise, your dog stands a very good chance of coming into contact with something, most likely bordatella (kennel cough) that they have no protection against. If you think daycare is expensive, try on-going vet bills.
