Sounds like he is turning into a man.
I have a female so not 100% sure though, and not eating seems strange though.
Try elevating his food bowl as some dogs as the get bigger don’t like a bowl too low when the eat as it’s a bit like eating upside down.
But probably is what you say in that Nemo is not mummy’s baby anymore lol.
He will ALLWAYS be my baby, he does not have any other choice!! lol
He just runs away from the bowl now lol. Im just gonna remove it and give him 2 chances aday to eat it. If that dont work I will put it up a bit higher or something.
