Titan lost ten pounds :( and 12 mo. puppy starting on diet

[wyoung2153]

Well since I started feeding raw Titan has lost 10 pounds. went from 96 to 86 as of last weekend. I am not entirely sure if it was because I was away for 2 weeks and my neighbor had trouble feeding him RMBs so if he didn't eat them she would just not give him any and he just had MM and OM. Since I got back.. about 2 weeks ago I foudn an RMB he liked, pork neck, and he doesn't hesitate to eat it at all. I switched to a premade raw that was suggested on here, Blue Ridge Beef: Raw Meat for Dogs - Cats they had a dealer in my area. He itches a lot so right now I took chicken out of the diet, as he already doesn't like it so I want to see if he's just allergic to it. He is getting 2 lbs of the Natural Mix, beef and organ meat a day along with some pork neck at night because the premade doesn't have bone in it. I add egg to his meal 3-4 times a week and sometimes plain yogurt. He also gets 3600 mg of fish oil a day. Does that seem right for him? Shoud I feed him more? Add some things? Maybe now that he is eating all his meal he will gain back the 10 he lost. Vet said he didn't look UNDER weight that he looked healthy, but she also said that when he was 10 lbs heavier.

As for the 3 mo. puppy. She is a Boerboel which means she should be around 120 when she is fully grown. She gets about 2.5 lbs of the Chicken with bone mix a day, I'll switch it up to the Natural Mix a few times and then she would get chicken neck or chicken back to go with it due to the lack of bone. She too gets Fish oil daily and egg 3-4 times a week with some plain yogurt on occasion. What do you think?? she is 35 lbs right now. Is that enough for her? should I add anything?

Advice and suggestiong welcome! Thanks guys!
