Story
Pickles is very sweet with me and my daughter (8yrs), she is often aggressive with new people. We've done our best but it's time to admit we aren't a good fit for her. We adopted her as a puppy and she's two years old now. Her mom is English mastiff/St. Bernard and her dad is from a long line of bovier de Flores. We did six months of training with pickles her first year. She's been such a gentle giant to me and my daughter. She used to be friendly with every dog she'd ever met except for our other dog, Gary. Gary doesn't like big dog. Something changed last year and she can be aggressive with people and other dogs. She chases our cats so we keep them separated. The home she came from had many cats and we were told that she never bothered them.
