Recently acquired two cockerspaniel/dachsund mix puppies. 6 week old male is black and tan and full of energy and love, a very small female(runt of the litter) who is also full of energy and love. He weighs about 5 lbs she barely weighs 3 lbs. My sister in law was going to take small female but backed out. Im having issues with our bull mastiff not accepting them and hes stopped eating and has nipped the puppies and growled at them. Im afraid they will get hurt by him since they are so small. So if anyone is looking for two loving brother and/or sister puppies please call me.thank you.
