Thank you so much for all your comments and suggestions; I really appreciate it. After Leela was dewormed last week and I incorporated can food to her diet, I noticed a change in her energy level. From a scale of 1 being the lowest and 10 being the highest she was at a 3, I want to say right now she is at a 4 going on to a 5.
Her meals are prepared as follows: IAMS puppy kibble mixed with Authority can food, table spoon of Nutri cal supplement, and and a table spoon of Missing Link vitamin and mineral supplement. The veterinarian recommended the Authority can food and suggested I did not change her diet anymore, until she gains a bit of weight. Also, the reason why I incorporated the Missing Link product to her diet was because she began to chew on the brick wall or scrape her teeth on the cement floor. A friend of mine told me it was because she was lacking something in her diet and it probably is due to a mineral deficiency.
Veterinarian wise, a friend of mine who currently owns a GSD with hip dysplacia recommended that I visited his veterinarian. He explained to me how this veterinarian actually did an actual physical exam, examined his joints, did x-rays, and conducted a blood test. I already scheduled an appointment with him this coming Wednesday. I must say though, I am a little nervous. I just hope everything is fine with her.
Thank you all for everything. I will keep everyone posted on her health and overall being. Thank you again.
