I had never heard of it either. I found out when the younger dog started viciously attacking its Mom. It’s a shame really. They were cute, but eventually the younger one had to be put to sleep because he began to bite people.

Harry the Beagle was deemed impossible for adoption and was put to sleep by the Rescue place.

Harry, the noisy Beagle.

The spaniels were adopted by a lovely couple, but when the younger one became addicted to biting, they were unable to cope.
