I have 6 hunting Beagles. They either a) have not had proper human socialization or b) they were abused. How can I help them gain my trust? Also, any training tips to help them learn to sit and come and their name would be greatly appreciated! 5 of them are 1 1/2 years old and 1 is 3 years old. Also, I have toys for them, but 1 (Duke) sniffs it but doesn't pick it up or play with it and the other (Bob) is scared to death of it. TIA
