Hello, I am a fellow newbie to the forum.
I just wanted to share a couple of things, first is that my last Bully was called Henry and what a fantastic name!!! Secondly, I myself have Spina Bifida, a very minor case, as in just 4 vertibrae, and I can carry on as normal, so I hope he is of similar status to me. I knew someone with a Bully with SB and they lived quite happily just had to keep their weight down slightly to ease pressure on spine.
I am so glad there are so many nice people on here, you for agreeing to take care of him and others who can help you through the process.
I wish you all the best and Henry is gorgeous, so is the Frenchie.
