How  much do you feed her at every meal?

The solution should be simple, feed a lot more LOL.

There are many reasons that could cause weight loss. The best thing to do is have the vet check her over to see if she has any health problems. I looked online and came up with a couple that could be the cause of weight loss. Which doesn't mean either of these are what your problem is. That is why it is probably better not to take a chance on someone else's theories and I would ask your vet to be sure. Hope everything is all right with her.

She don't have worms, cause she gets her pill monthly!!

Also,

Mom kinda thinks it might be thyroid problems.

Mom feeds me,  Purina One Dog Food.

She is giving me alot also, but I don't really eat it Dx

Alrighty,

Mum don't know if I like green beans but she will try.

she could still have worms. just because you dont see any in her stool doesnt mean that they arent in the intestines

Pets (like people) who lose weight even while eating an appropriate amount of food is not normal and can be dangerous.

Speak with a veterinarian. Monitor his weight. Weight loss can be caused by many significant health problems. Do not let anyone tell you to "just feed him more" or "It is not a serious problem." - they are wrong and giving you bad advice.

Question: You treated him for heartworm? I assume he was DIAGNOSED with a heartworm infestation and treated with injectable heartworm medication and the veterinary office.

Rocko had the same problem he would eat like a horse but wouldn't gain weight and he would look skinny and like we weren't feeding him...

the vet said there was nothing wrong with him, its just that he was still a pup and was so active that he would really just burn everything off so he would look skinny...

he's still really active but after his 2nd birthday he started to fill out more, and he eats the same amount as before... he still looks lean but not skinny like before... idk how old your dog is but maybe that could be it. 

Oh and exercising them until there worn out really opens up there appetite, i've noticed this with Rocko and Zasha, if I go running with them, that same day at meal time they eat a lot and they finish there food quickly... try exercising her and of course wait a couple hours until you feed her, i'm sure she will eat all her food.  

Lizzie meantioned adding green beans. Green beans are very low in calories. Some people add green beans to kibble, but that is so the dog can loose weight, not gain.

Victoira:

The only thing why I keep asking people, is that my mom Angel might get rid of her if we can't get her to gain any weight.

I also, tell my mom it could be that she runs it off.

But, I also might thinks its thyroids.

Cause, the vet never said that she had a intestianal perisite or anything.

Also, we are thinking about getting her this Grandma good..

CRAPPY I forgot what it was called Dx

But it looks really good.

Kahula deary when we first got mattie she was skinnier then you dear now she her natraul weight and height and has healthy as can be.

We got her checked at the vet of course and ran test's for any problems (her old owner abused her badley and had a nasty house)

Well Mattie get's a mixture of kibbles and bits brush bite's and a half a cup full of dog sauce you can get at pets mart or incridipet, and Mattie take's one doggy vitam everyday and has 3 meal's a day But we also trade up the sauce's every few days so she won't get tired of the dog food mixture's..But give her some good hard dog food (good for teeth) and some of that doggy sauce and maybe a tube of doggy vitamen's.

Also feed her some table scrap's every so often but not everyday because it can be harmful to her but don't get her used to getting human food trust me Bit Bit has a bad habit of getting human food so used to it she is super aggressive toward's people who get near her when foods around 0-0 but yeah try that maybe or check food out on pet helping site's or check with your vet =]

I hope this will come in handy or help out a bit =]]

Victoira:

Im  thinking about getting Iams, and get that Iams sause stuff, to place on my food.

She also loves getting little soft food for treats, Im thinking about putting a pack into my Iams food, every other day.

Also, we feed her table scraps sometimes to like gravy, and everything.

Victoira:

We just got Beneful today,

and also got some Crabs from walmart xD

Beneful? Blugh. Definitely not the best you can do IMO.

A dog food should be meat based without harmful grains like corn or wheat. It also shouldn't have chemicals in it like all the dyes Beneful has in it Dx

I'm not going to try and convince you to switch, but if you just take a peek at the ingredients of Beneful compared to FreshPet dog food, you might notice a difference in how healthy the food really is:

Beneful:

Ground yellow corn, chicken by-product meal, corn gluten meal, whole wheat flour, animal fat preserved with mixed-tocopherols (form of Vitamin E), rice flour, beef, soy flour, sugar, sorbitol, tricalcium phosphate, water, salt, phosphoric acid, animal digest, potassium chloride, dicalcium phosphate, sorbic acid (a preservative), L-Lysine monohydrochloride, dried peas, dried carrots, calcium carbonate, calcium propionate (a preservative), choline chloride, added color (Yellow 5, Red 40, Yellow 6, Blue 2), DL-Methionine, Vitamin E supplement, zinc sulfate, ferrous sulfate, Vitamin A supplement, manganese sulfate, niacin, Vitamin B-12 supplement, calcium pantothenate, riboflavin supplement, copper sulfate, biotin, garlic oil, thiamine hydrochloride, pyridoxine hydrochloride, thiamine mononitrate, folic acid, Vitamin D-3 supplement, menadione sodium bisulfite complex (source of Vitamin K activity), calcium iodate, sodium selenite

FreshPet which is often available at Safeway:

Chicken, eggs, chicken liver, chicken broth, carrots, brown rice, peas, rice bran, carrageenan, salt, natural flavors, Choline chloride, vitamin E supplement, niacin, biotin, riboflavin supplement, manganous oxide, thiamine mononitrate, vitamin B12 supplement, vitamin D3 supplement, pyridoxine hydrochloride, folic acid,
Calcium carbonate, zinc proteinate, iron proteinate, ferrous sulfate, zinc oxide, copper proteinate, copper sulfate, niacin, manganese proteinate, manganous oxide, thiamine mononitrate, calcium iodate, sodium selenite

The FreshPet sounds a lot healthier than the Beneful huh? It's also all-natural with No preservatives which is why you must refridgerate it. Juno is fed FreshPet natural rolls and she is doing wonderfully! :-D

Joey:

I know we could do better, when when we looked for Iams they didn't have it Dx

Silly store!!

Tinkerbelle:

I really like beneful, I go crazy on beneful, and are vet never said anything bad about beneful eaither.

Umm.. We really don't have FreshPet food here,

and we can't buy anything off the internet.. :/

Tinkerbelle, dogs don't have the enzymes to break down raw vegetable matter. Not sure where everyone got the idea Iams was such a great food...

Yuck. 


Anyhow by looking at how thin you are in your picture; hips protruding at that visibility is not normal. There could be many factors contributing to her weight, for instance she may be diabetic. I would get her scheduled for a vet appointment as soon as possible. If nothing is found after the visit, put her on a high calorie puppy food, that should bulk her back up in the case there are no outlying factors.
