Okay, I've had a Newfoundland bitch which is about a year

you need to stop sharing your food with her and only give her whatever dog food you want her to have. don't give in after 2 or 3 days of her not eating and give her table scraps. make her finally give in and eat what you want her to eat.

she's been checked out by a vet, right?

A professional vet told you what to do, so listen to them. She will not starve herself to death, stop giving in. If you can't take care of this dog properly, then get rid of her.

Try excersising her for more than her usual time so that she has an appetite. Other than that, STOP letting her have other food or table scraps. You could try switching to a new kibble, but don't do anything else. She will it, but unlike us dogs can go a good three or four days without giving in to their stomachs so ignore her.

The problem is, OP, is that she is too smart for her own good. Basically, she's figured out that if she waits long enough then you will give her whatever she wants.

This is the dog equivalent of a human child throwing a temper tantrum until the parents give in and feed the child candy and ice cream instead of vegetables.

Listen to >>2034839 >>2034846 and your vet. Go back to feeding her kibble, once she starts eating that again then gradually re-introduce her to raw meat every other day.

Three times a day, put a bowl of kibble down in her designated area, make sure she knows it's there. If she doesn't eat it within 30 minutes, pour it into a tupperware container, close the lid, and put it in your pantry where she can't reach it.

She's smart enough that eventually she will figure out that if she doesn't eat when you say she will, then she won't eat at all.

Also, stop taking her to your dad's. Or at the very least make sure she doesn't get any kind of access to food while at your fathers.
