Hi,
I was hoping for some help for a friend, we just visited her house and she recently got a new puppy who is just lovely.
Their original dog is a 4 yr old bitch who is undesexed, suddenly started to growl and bite the kids when they tried to play with the puppy.
We have known the older dog her whole life and never had an issue with aggression before.
Can anyone advise how to handle this problem ? I am not sure if she is jealous or thinks it is her puppy and is very possessive over it.
I ended up crating the older dog so she could not attack the kids anymore but she continued to growl at them through the cage.
