When Athena, Angel and Luna where puppies I would touch there food, put my face in there food remove there food have them sit before getting the food back, make it so the food being moved did not bother them, so I far its work great. I never had any issue with Athena in her 10.5 years, Angel same thing she is great with food if you get down in her food she will just sit back like she is saying ok let me know when your done LOL, Luna is still a puppy, she is also different from the others, she is very food driven so the process has been long. I took lunas bowl and she would circle me then sit, I would out the bowl down, then I would put my face near her bowl and she would lick it or eat faster than I would put my hand in the bowl or blocking the bowl, she would sit and just wait. When Angel is eating Luna is in a different part of the house, when it comes to water they both drink fine, never any issues well Luna will jump around the bowl and flip the bowl over making a mess but besides that never any resource guarding issue. Also I never never let the kids touch the dog when eating, I tell my nephew and niece to leave them alone while eating. I do not think I would have a issue but no need to start one either.
