she is a lovely little cavachon pup whos obviously misses her litter mates. she doesnt whine at night now but if she is not with me all the time she whines so loudly. i have been thinking of getting another puppy of the same age to keep her company is this a good idea?

12 weeks is much too late for puppy to leave its mother, 7 - 8weeks is the correct age - look it up. this is not my first puppy but my first puppy that whines and is so clingy. maybe i shouldve stuck to a proper dog such as a golden retriever that ive had before.
