Ok so we have a ten week old puppy and an older ( 6 year old) dog. We have had the puppy 2.5 weeks. They are constantly growling at each other and puppy is jumping at our older dog's face. They are extremely possessive over toys, each wanting what the other has. My older dog is jealous whenever I give the puppy any attention. We are trying to give them time away from each other. I really can't work out whether they are play growling or hate each other , sometimes our older daog barres her teeth, she has never hurt or bitten the puppy.
Will things get better ? I'm not sure how much longer I can bear to watch elder dog being so stressed. Any tips welcome.
