Supplements for older, neglected dog?

Without doing too much too fast, I think good general supplements are salmon oil and vitamin E, and Knox Nutra Joint for older dogs.

I give my 3 goldens, ages 11, 6 1/2 and 4 1/2 a fish oil, an EsterC and a Dr. Foster & Smith VitaCap every day.    The old man also gets a couple of MSM/Glucosamine caps in the morning and one at night as he has a little arthritis.  he also has to take thyroid tab twice a day.  My 6 1/2 year old golden girl has had both knees operated on for luxating patellas, and she gets one MSM?Gluco in the morning along with a synoviG3 chew I get from my vets.
 
I would talk to my vet before giving anything, and as sooner said, i woudl start a little light on the sups.  If she has been undernourished, you don't want to over do it to fast.

In addition to the supplements listed above, you may also want to try bovine colostrum. I would also reccomend tripe; you can get the canned version from Tripett ([linkhttp://www.tripett.com/]http://www.tripett.com/[/link]).

Thank you for taking in a senior GSD.   I agree with your suggestion of a vitamin/mineral  & glucosamine tabs.  I buy PetTabs at Petsmart.  Also add  Salmon oil.  Has she been to the vets for a check up?  If not she needs a full exam, x-rays and bloodwork.    Good luck and keep us posted on her progress.

I would also make sure she does not have hook worms which would also make her so skinny and comprimise her immune system.
Have you had her HW tested yet?

We just "rescued" her yesterday, so she hasn't been to the vet yet. I, of course, will get her in as soon as I can.
She is eating, although she doesn't seem to have much of an appetite. I think she's more concerned that someone is going to take her food.. the whole time she's eating, she's hunkering and looking around. If you approach her, she walks away and that's it.. she won't go back. I have a feeling the other dogs from her household bullied her quite a bit, maybe? I've left our other dog outside while she eats.. to give her a sense of security and eliminate her desire to cower under the "pressure" of another dog.
I'm hoping to see some improvement in her appetite once she realizes no one is going to beat her for eating or take her food? I really don't know the situation she's come from in dteail. All I know is her owner moved and left her with his former room-mates who also have a greyhound and a pitt bull. For three days (that we KNOW of) she was left chained outside with no food or water. She was nasty and matted, when my hubby brought her home yesterday. Wish us luck, you guys... we're going to need it.

I took her to the vet today. She has hookworms, and infected scratch on her gum, a minor skin allergy and a boarderline thyroid issue that we will have to keep an eye on. She also has minor hip displaysia.
The vet recommended a senior feed (which I was feeding her already), gave me a dewormer, antibiotics and shampoo for her allergy, which he thinks will clear up once she is back to a normal, healthy condition, and also recommended a senior multivitamin. Other than that, she is good.. and no heartworms.
Just thought I'd give ya'll an update!

Thanks for the update.  I'm happy to hear that she is in pretty good shape.  After the deworming, antibiotics etc I'm sure you will see a huge improvement.  Good luck!  Please keep us posted.

Yay! Please do keep us posted, you probably got her just in time. She ought to bounce back well, please do keep us posted.

Congrats on your latest addition! You are such a wonderful foster mommie. She will probably do much better once the worms and etc are resolved.
 
I would (personally) put her on VitaCaps and a joint supplement. I fed the Joint Care 2 (has MSM and C/S combo). I know I sound like a Foster& Smith saleman, but I actually just found it was easier and cheaper for me. If you do get those, do it online. Get put on the dog email newsletter thing (sends online sales and discount info). Soon your email inbox will have a discount/coupon to use on your order. Heck, every penny helps!
 
I would start with some quality walks, etc to help her build up her strength and endurance. You most likely already know all this, but thought I would mention. I think what you are doing with the feeding situation is not a bad idea - at least till she settles in and gets comfortable with her "place" in the family.
 
Does she have a name, photos? Congrats again!

might I suggest checking out dog.com for supplements BEFORE buying from someone else?  They ARE the sponsor for our forum, and I do know that they price match.

I DITTO Glenda's post!   Dog.com Store ROCKS!

Great prices, great deals, and a HUGE selection, that you cannot beat anywhere else.

You and your hubby are wonderful humans to take her in !
 
I adopted a very shy and nervous neglected boy.  He too was overly submissive and let our resident bulldog take his food.  I finally got smart and started to feed him outside on the porch by himself.   He prefers eating w/o anyone watching or being close, plus he eats very slowly..  So you are wise to feed them separately.  However, I would feed the resident dog inside and the new dog outside,,,just to let the resident dog maintain an alpha status. 
 
For an older dog, fish body oils and Vit E , ESTER C all help with arthritis.  I have started my 9 year old on KNOX ULTRA JOINT as a preventative.  I have SYNOVI joint supplement but never used it.

Thank you all for the info. I really do appreciate it. I did talk to the vet about joint supplements and exercise. He felt it was best to start slow. Just allowing her plenty of exercise time in the yard for now, then once she's more adjusted and in better condition we can start with short walks, and increase as we feel she would be comfortable with it. The same with the joint supplements. We're going to concentrate on just getting her to a healthy condidton, put weight on her, etc... and then possibly add a joint supplement. He recommended not adding too much too fast, for fear it would upset her system. She has a recheck in four weeks. We're going to go from there. During this first month, we're just going to concentrate on getting her healthy, and try to reverse the affects of the malnutrition and work on building her socially.
Thanks agin for all the good info and support! YOu guys are great and extremely helpful.
