lots of gremlins in the machine always, im away for the night, Alfie with me on his hols, if you want to ring me to know more about him thats fine, just check with one of the rehoming girls first as i think you need to put in an application for the dog you are interested in. As to your questions, he is about halfway to knee height, he barks when there is something to bark at and is quite vocal when playing 
!!!! If your dog is timid or submissive its a no go for our Alfie 
Like i said he is living with a large golden retriever bitch and they are good pals
