[[My sweetheart Hiccups]] ?
I named her Hiccups cause she's always have hiccups. She seldom barks or bites and always hiding in her picnic basket. Is it consider as a shy puppy?
P.S: She's a beagle.
Chances are, she was poorly socialized. How old is she? Don't put sour socializing her. There is a critical time period when a dog must be socialized to different people, animals, and scenarios. If this doesn't evolve, they will be difficult to bring places.
For example, a dog that hasn't been introduced to riding in cars while it was a puppy may never be capable of go on road trips with their owner.
