What should I do? My dog is steady losing weight, making a slurping noise when he eats along with trembling. I change his food from dry to wet.

The slurping noise could simply be from eating a food with more moisture instead of having to crunch the dry kibbles. Trembling can be caused by so many things. To name just a few: pain, anxiety, muscle problems, neurologic problems, toxic exposure. If he is steadily losing weight but eating well, I would feed him more! If he doesn't gain weight in 1-2 weeks, he should be evaluated by a veterinarian. Also, you can use an OTC pet dewormer and see if that helps. If Tobias develops vomiting, diarrhea, or does not show a great appetite, I would recommend that he see a vet as soon as possible. Potential causes for this include dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others.
