She is 15 yrs old and used to be the sweetest girl, totally loved me, slept by my side all night but she keeps biting me. Not just a little nip but full on snarling, last time was so bad I was very nearly hospitalised and i had two lots of antibiotics.
She looks at me as if she hates me and is just waiting for the opportunity to attack me, I'm so scared of her now I actually had a nightmare about her trying to kill me.
Any idea what is wrong with her
