I have a beautiful healthy 3 yr. old sheperd who will not gain weight. Max has been very patient with us as he undergoes test after test. Poor guy! Thank God there is nothing going on with him. We currently feed him a high protein diet mixed with his regular food twice a day. However, there is always something left in his bowl. Is there a good food out there that will help him to gain weight or any good recipes I could add to his food? Expense is no issue! Any suggestions would be great! Thanks in advance!

I have had a similar problem with one of my poodles, there is nothing medically wrong with him, he is just off his food.

Dogs can get bored with eating the same thing day in, day out so everyweek I add something new to make the food different but keep the same base ingredient.

Mine get dog sausage (dog roll) that I dice into cubes.
I then microwave it for 30 seconds to soften it further.
I then take a handful of raw beef mince and mix it through th dog sausage.
You will want to wear gloves as it is not pleasant.
Mine picked the meat out the first time I did it so you really havr to squish the meat into the dog roll and make a nice chunky paste that they can't pick bits out of...

Alternatively you could use canned food or soaked dry food if you do not like dog sausage and add mince to it.

It worked for me, Brody went from not wanting his food at all to polishing the plate just by adding a little heat and raw meat!

If you can get your hands on some lamb flap it is great for adding weight, it is fatty though so only feed a very small amount to start with and build it up over a week, once the dog has added a little weight you can stop using the lamb and feed regular food.

How much does Max weigh. Shepherds are not the best eaters but they eat when hungry. My current shepherd weighs around 90 lbs. He was a skinny rail of a dog until about the third year. He was about 76 lbs. He filled out as he got a bit older. If the vet found nothing that's good. My dog is 11 now and always gets 4cups aday once aday of eagle pack natural. He almost never finishs it . I leave it down if he is hungry at night he will eat more.
Do you feed once a day or twice? Maybe you want to leave the bowl down for him.

Same here. I have a white German Shepherd, and no matter how much I fed her, she was just a bag of sticks. Still is, for the most part, though after her third or fourth year, she started to put on weight and keep it on. I think sometimes with Shepherds it has to do with time. Sorry I couldn't be of any more help than that...

Bribing a dog with rich food is NEVER a good idea. It creates an unbalanced diet and by the time symptoms show up, the pancreas or liver may be fatally damaged.

As the last 2 suggested, leave well enough alone. That is how many Shepherds are.

It's not bribing, it's just making the food more interesting.

Personally I would hate to eat the same thing day in day out which is why I use the same base ingredient as I said and add something to it (about 3/4 original food to 1/4 added 'flavour')
