Resolved Question:

How can I fatten up my skinny boxer dog? She is a lot skinnier and a lot shorter than my last female boxer at her age. Marley is only 50 pounds and is a full blooded boxer as 75% is German boxer and the other 25% is just a "normal" boxer.

Welcome to JustAnswer! I would be happy to assist you. I am a 2003 graduate from UC Davis and a Medical Director of a 4 veterinarian practice.

Skip the raw egg. Not worth the complication of a contamination issue making Marley really sick.

Absolutely, must do a fecal test.

Bring in a fresh poop sample to the veterinarian. Ideally, within a few hours. Request that it be sent “OUT” to the laboratory instead of being looked at in the hospital (more accurate that way). We are not interested in only worm eggs, but also checking for the very common microscopic bugs like giardia and coccidia. These types of parasites will not be cured with over-the-counter dewormers. Giardia can also be difficult to identify on routine fecal tests, so ask your vet if they always add a “giardia elisa” to the fecal test. Here is more detailed information about fecal testing:

Especially, with a simple giardia or coccidial infection, to easy to miss not doing this test.

Otherwise, the extra meal and adding additional food to each meal is the easiest way to complement Marley's caloric intake.

But, you should have your vet evaluate Marley. Find out what is her BCS (body condition score).
This is a score of her body weight relative to her body frame, and important for helping to determine who underweight she may be. Boxer's are really ideally lean dogs, and it is nice keeping them trim to help with future orthopedic issues in older age.

That is how I would proceed. Exam, fecal test, and the BCS score to see where you are at, and what weight needs to be gained.

Good Luck
