awww sounds like she has really been through the mill poor little thing, hope shes fully better now.
Its bound to have affected her to have had all that going on, but I really think if you stick with it you will see results fairly quickly. Maya (puppy) was a nitemare when we got her I really did at one point wonder if I'd done the right thing, my house was being trashed and I was worn out with it all. I've not had a puppy in a long time and I had no idea, niave of me to think that I was getting a 6 month old trained pup....wrong!! I really was wondering last week if there was any light an the end of the tunnel yet a week later things really are different.
I think aswell as I thought she was trained I let her have too much freedom to quickly. She had the run of the house which was silly and that resulted in so many accidents. Now shes only allowed in the rest of the house if I'm with her and that really helps.
She doesn't yet know how to tell she wants out so thats the next stage am just grateful shes going outside and not on my rug!
next thing for us is the car....she hates it! she messes as soon as we leave the house. So she is now in her crate going round the block everynite its less than 5 mins but 4 days in shes not had a clean run yet so its not all a bed of roses here yet either lol
put some pics on if you get chance would love to see her!
