Hi, I have a Cocker Spaniel puppy (almost 9 months). She was the runt of the pack and is still smaller than her siblings. She is extremely unfriendly with other people and very unpredictable. Will play with our German Shephard and the next moment attack her if she comes near her toys, Even if Skye walks away she keeps going after her. So I am a bit worried about the degree of aggressiveness! She is extremely loving towards us and wants lots of attention. Please let me know your thoughts and send me a quote. Thanks.
