Hi everyone! I just got a teeny tiny chihuahua puppy and I need some tips on making her relax and comfortable. She is a sweet puppy, very well behaved. She was the runt of the litter, so she is teeny tiny and will only be about 3 lbs full grown. She has a comfortable crate lined with baby blankets and towels, as well as all of her food, water, etc. We talk to her in soft voices and pet her/pick her up, and she's completely fine. But I think she misses her biological mom, dad, and 500 brothers and sisters. (All the other puppies of the litter were present and playing together when we bought her.) We bought her by herself, so she isn't really going to have a puppy playmate, just me and my family. We are very nice to her, and are trying as best we can to make her comfortable. But she is kind of shaky, and nervous. I'm hoping she gets very relaxed and even starts barking in a few days. Any advice?
