Dog lethargy. Weight around 40kg!

Hi dear, Appetite loss is ur main concern about ur dog. (Here is my small video link on this topic- https://youtu.be/1q3rnqapzme?si=c_vun3DH2L8XhGmM ) So, Loss of appetite and lethargy persisting for 11d is a matter that requires urgent vety attention, especially in a normally active breed like a Golden Retriever. While it's good that she is drinking water and occasionally eating eggs or dog biscuits, this pattern is not sustainabl especially for a dog her size (40 kg). Vaccinations given 12 d ago are unlikely to cause such prolonged symptoms, so it’s important we don’t overlook other potential cause,,such as GIT issues, infections, organ dysfunctionor pain. I strongly recomend a thorough clinical examination at the earliest. Blood tests, abdominal palpation, and possibly imaging (like X-ray orultrasound) may be needed to identify the root cause. Please don't delay any further — early diagnosis leads to better outcomes. Wishing her a speedy recovery, 🙏
