My dog ate a big lamb ear. Is her lethargy a stomach issue?

I certainly see what you mean about the swelling around Roo's ear! It could be a swollen lymph node, which is an indication of infection. Given that it's on one side and she is eating slowly, it could be that she has a tooth root abscess on that right side leading to the swollen lymph node and slow eating. The warm ears could be due to a fever but also an ear infection. Given her multitude of symptoms, it would be best that Roo is seen by a vet. The vet can diagnose what is causing all her symptoms and can treat her accordingly. Because she has been lethargic since Wednesday, it's best that she is seen by a vet tomorrow.

If Anfinneg has never had a pig ear before, it could be making him nauseous leading to the drooling. I'd keep an eye on him for now and if he's still drooling a lot in the morning, have him seen by a vet.

She may have ingested something that isn't agreeing with her GI tract. Monitor her and if the symptoms worsen, seek veterinary attention. If not, withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet ( boiled boneless / skinless chicken and plain white rice) in small, frequent amounts. Serve warm or mix in a teaspoon or two of baby food to stimulate the appetite. If her appetite does not return or she begins to vomit, see your veterinarian.

Her stomach may be upset because of eating the sticks, because of the diet change, a combination of both, there's no way to tell just from her symptoms. It may be that there is a piece of the stick still inside causing an obstruction or pain. I recommend getting her in to see your vet for an exam, possibly x-rays, right away if she starts vomiting again, develops diarrhea, continues to refuse food, and/or continues to be lethargic. If there is an obstruction or perforation somewhere in her GI tract, getting her sooner ir better than later, as this condition could require surgery.

Based on your description, it is difficult to say for sure what is wrong with Gracie. I would recommend having her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I would recommend having her blood tested and consider x-rays. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I can certainly understand being concerned about Tulip! Lethargy is a very general sign of illness, and it can be caused by systemic illness, infection, inflammation, or injury. I would keep an eye on her tonight, and if she is still acting this way in the morning I would take her into a vet first thing for a health check.

Antibiotics can cause an upset stomach leading to a decreased appetite, but I'm concerned that it's excessive and Simba has other symptoms going on. If the ear infection is severe, it could cause these symptoms but I can't say for certain without seeing him in person. I'd take him into a vet immediately to get checked out.
