I have a 3 year old fox terrier he is losing weight. He eats normally and goes to the bathroom regularly. His attitude hasn't changed. I have him on healthy weight blue wilderness food. I was wondering if that would cause him to lose weight instead of gain it. I have taken him to the vet but I can no longer remember find the food that they want me to feed him, it is something for high strung dogs. Any suggestions?
Type of Animal: Fox Terrier (Smooth)
Name of Dog: Goerge

Hello, there very well is a underlying medical cause for what is going on.
Weight loss in dogs can be due to a dog that exercises A LOT, and doesn't eat enough calories,
due to intestinal parasites (not just worm issues, but very commonly with microscopic bugs like giardia or coccidia).
Which supports recommendation #1. Must do a fecal!
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:
Endocrine diseases like Addison's can cause weight loss, even if no other symptoms.
Problems with protein loss through gut or kidneys.
Which brings me to the suggestion that your vet should do a basic blood and urine test as well.
That's where I would start!
Certainly, if basic testing is normal, THEN, you could focus on a more caloric diet and feeding more often.
