Hi , we are looking for our first ever dog for our family. We came across this cute Brittany spaniel and mini lab mix . Are they good for a house with small kids? Also the rescue group is in Carolina and we live in NY. Is it safe to get a puppy like that . They say that they will deliver the pups once I give them deposit online. This rescue group is called mustard sandwich resue .please help. We are also considering beagles and dachshund mix. Which breed would be more of a match for us. Thank you Raji
