It sneaked up on me, honestly.... I touched her, today, and didn't feel a rib. Huh? I pressed. Whoops. She's got a little bit of padding, over her ribs. Wow, that has *never* been an issue before! So.... she's eating Hills Z/D, which is 14% protien, and 10% fat. She has an appointment for allergy testing, on Tuesday.
The deal is, she's lost visible muscle on this food. She's been eating it for 3 1/2 months, now. She obviously needs more protein. She's a little lacking in stamina, also (I know, I should count my blessings, with the calmest PRT EVER), and I've been a little concerned with that. I'm not really feeling the urge to cut back her food. I'm thinking about just waiting til her allergy results come back, and evaluating her diet at that point. I'm thinking that when her fat and protein gets boosted, she'll be able to put the muscle back on and be ok.
Am I completely backwards? This dog, BTW, has a history of not being able to keep weight on. She weighed 16 lbs until she was 3 1/2, and finally put on enough weight to not look like skin stretched over a skeleton. Since then, I've been able to feed her pretty freely without any weight issues (ya know, no limiting treats or bones, and a reasonable amount of food in her bowl). I'm thinking it's just the high carb/muscle loss thing that's got her off.
