Pixel's eating issue +
Pixel, a 12 yr old Jackapoo, had readily eaten ~1/2 cup of mostly the same brand of dry food 2X per day for 11 1/2 years, then one day she abruptly refused it. Since then, for about 8 months now, she accepts new food brands for a couple of days then doesn't eat them either. Her vet says dogs won't starve themselves and that she's just holding out for tastier treats, and advised me to just leave the dry food out and hold my ground, since that's better for her. She does love her tiny Milk Bones and veggie treats. She's gone from about 25 lbs. to 18 lbs. During this time her hair has matted more than ever, too. Otherwise, she seems fine. Her 18 lb. weight is actually a better weight for her 13 in height. Any ideas?
