Aggressive 1 year old female Leonberger
Hi, our puppy is a big softie, very good and patient with children and people. She was also very friendly with all dogs until the day when we went on our holiday and put her into a dog kennel for a week. We have noticed straight the next day when my partner took her for a walk that she was aggressive towards other dogs. As she went into her second season we thought it could be related to that and I was hoping this would change. Unfortunately her season is ow over and she is still the same. We have contacted our dog trainer and we are planning to see her next week for an assessment. She has also recommended to have a vet check to eliminate any physical issue.
The dog kennel said to us there was no problem with our dog while staying with them but I am wondering whether she has had a bad experience with other dogs there or maybe just completely freaked out by being somewhere else? She has stayed in another kennel before and except for a little bit of confusion, she was fine.
Not quite sure what to do on walks now, we walk her with a muzzle and it is not a busy area. Just don't want to make things worse.
Thanks for your help.
