Hello everyone,

I own a 14 month old Siberian Husky called Tifa, and she is usually a very friendly and affectionate dog...even now she is snuggled up around my feet.

We thought we had her reasonable well trained, she will sit if asked, stay, leave stuff alone if me or my partner give her the command "leave it" and also fetch stuff. We also followed all the advice about eating before her and pretending to munch on some of her food before we gave it to her in order to establish our selves as higher up in the pack then her. She is not allowed on the sofas or bed (but I must admit that every now and then she does get on and we let her stay)

She also gets plenty of exercise, walks and lots of playtime.

However just recently (over the last month) she has had odd, out of character moments, for example my girlfriend had just finished playing with her, told her to sit and then gave her a chew...when my girlfriend then went to pet her she growled and showed her teeth at her. Aimee could not get near Tifa then and so she had to wait for her to finish the chew, and then she got a tap on the nose and a firm 'NO'.

The other week I came out of the toilet to find Tifa had got upstairs, and she had found a box of chocolates....I went to get them off her and I got exactly the same treatment....however I was able to get the chocolates off her quickly and then I tapped her on the nose and said bad girl and put her in her bed.

We have also had trouble at the end of the night getting her to move out of the front room into her bed...I have to go in the kitchen and call her and pretend I have a treat for her to coax her out....failing that I pick her up and march her into the kitchen.

Last night my partner was going to pick her up and push her in the other room when she started growling and showing her teeth again....I stepped in with a firm voice and told her no and she snapped (but did not bite) at me...so I grabbed her muzzle and slapped her on the noise and told her NO!...and then she bit me on the finger and left quite a nasty cut. I put my hand straight round her neck and pushed her to the ground and held her there until she calmed and stopped growling and then I was able to put her in her bed with no more trouble.

This morning I have now decided to keep her out of the living room full stop...we have just had a play and now she is asleep on my feet.

Have any of you had similar problems, what could be the cause and what should I do, she is normally a really friendly (if somewhat stubborn) dog ?

PS - Sorry for the long post, especially for my first one lol
