I have an 8 month old rescue pup - mastiff X - maybe? Long story short, after trying training days, small training classes and one on one training, I ended up with a consult at a behaviour vet. Indi (the recue pup) was diagnosed with a mental disorder leading to anxiety. This has manifested itself as nervous behaviour when meeting new people and this is slowly escalating into barking / growling. Note that following an introduction I can get Indi to relax and even to start playing with the strangers, but there is obvious stress to Indi and for most people her barks and growls (and size - she is 32kg and jet black) are very frightening
She has also started displaying aggression towards other unknown dogs. I also have a mini dac at home and they have now been separated following a fight where Sam (the mini dac) was injured. At one of the training classes, another dog growled at Indi and her reaction was intense, lunging, growling and barking. I was able to keep control and following unsuccessful attempts at calming her I removed her from the class and went home.
The behaviourist has perscribed medication and behaviour modification training including walking on a halti, calm on command, crate training and following the NILIF principle. I am not keen on the medication but feel it is probably necessary in order to modify her behaviour.
It should be noted that she is beautiful at home, very firendly to my family, we can remove food from her, she sits and stays on commands, even knows how to roll over. Once outside and there are distractions present she will not follow any commands, even food treats won't entice her. At the large group training classes, it got to the point where she was choking herslef attempting to get to the other dogs. I am starting the management methods for her today and right now it all looks very difficult.
Any advice is appreciated
