The best next steps would be more tests to help get to the bottom of her symptoms. Typically we start with xrays and ultrasound if bloodwork is normal. Mainly looking for any cause as lethargy and weight loss are non specific. If nothing is found on imaging then loss of nutrition via the GI tract is possible and so sometimes additonal testing is needed to assess this. If your family vet is stumped, some pets get referred to see a specialist (a veterinary internist) for additional help in diagnosis. Additionally medications can be tried to help with any nausea/stimulate the appetite but if an underlying cause can be found and treated that will always be better. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
