German Shepherd dog

Start with a trip to the vet to find out what's wrong.

can you please let me know examples of raw diet

First get a wellness checkup, CBC and BCP @ your Vet.  Keep and Study results. RAW/BARF diet  to compliment levels and plenty of exercise. Also, the CBC/BCP will tell you if primary treatment is needed IE: kidney failure, allergies, autoimmune diseases, anemia, leukemia whatever. Good Luck.

Yea and pretty vague too......healthy could be different depending on who you ask.

I don't think it's a strange question. I think it's a question asked by a non-English speaker who may have translated it from his native language using an online or other dictionary. My guess is he's meaning to ask how to make a dog look his best within a short period of time. Maybe he wants to show him, or sell him, and is looking to get a shiny coat or something.

But yes, it would be helpful if  the poster could ask specific questions or address specific issues about the health or appearance of this dog and whatever it is he wants to improve.

Yes, if it's to CONDITION a dog, such as tone its muscle, build its endurance, and generally improve its health, then yes, a raw diet would be beneficial.  A vet visit is still in order just in case, as before starting ANY exercise program, a visit to the doctor or vet is in order for human and animal alike, especially if the individual has pretty much been a couch potato (inactive).  Build the dog's endurance like you would for yourself- start by walking fast or jogging slow, don't go far, pay attention to the dog for signs of exhaustion, don't do this on hot days, examine the pads frequently, and give plenty of time for a cooldown walk.  Swimming is great for endurance and running in sand is great for toning muscle.  Biking with a dog is a great way to build endurance.  Feed high quality kibble that is low on grains, preferably no corn but this varies with the individual, and make sure there are lots of kcals per cup for energy.  Groom the dog to remove loose and dead hair.  Do lots of fun training, mental work, and bonding, because a physically beautiful dog will be absolutely stunning and glowing if it's well adjusted, enthusiastic, and ready to go!  We got our rescue dog looking great by upping his exercise, putting him on raw (with plenty of eggs, olive oil, and fish oil amongst other goodies), and building his muscle, not to mention lots of training!
