I believe by now your neighbour has no doubt as to your ability to take care of pets, you have really done well with this beautiful dog.

One can actually tell that you are quite detailed when it come to looking out for this precious dog. It takes patience and time to study them and I'm glad you have put in the work, so it not a coincidence that it now understands your routine, diligence brought the result.

By the way, what gender is your dog, I didn't pick that all through my read. If it's a female, then be ready to have many more dogs around you and if you feel you won't be able to handle it, you can gift someone capable of taking care of it around you...just like you did.
