My boxer threw up weeds and is lethargic. When should I worry?

As these episodes are very commonly related to dietary indiscretion, I would recommend to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, more severe lethargy or inappetence. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

It's always a reason to worry when a dog vomits! Given that Bosco hasn't thrown up in a little bit, I can give you a home remedy for him to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

Poor puppy. That looks like digested food that he vomited up. He may have eaten something that he shouldn't have. Therefore I would try to fast him for 12 hours and then offer him small amounts of boiled chicken and plain rice. If he is still vomiting, lethargic, or has lack of appetite and diarrhea, then I would be concerned he may have either intestinal parasites or has contracted the deadly parvovirus. It is best to have him seen by your local veterinarian if he is not getting better. Hopefully he just got into something he shouldn't have and will show improvement within the next 12 to 24 hours. Best wishes with your puppy Mac and I hope he does get better soon.

This may be from an allergic reaction from a bite or sting or something in the environment. In severe cases, vomiting and lethargy can occur and be related. However being a puppy, he does need to be seen by a vet to make sure there is nothing else going on such as a viral infection that is causing the vomiting and lethargy, parvo. Your vet can examine him and check for parvo if needed and determine if it is all a reaction or something else

Throwing up can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Juice for 24 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the vomiting or if the vomiting increases, or if your dog gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on

Poor Oscar sounds like he isn't feeling well at all lately! He could have a severe GI illness, may have eaten something rotten, could have a foreign body, or could have pancreatitis. It is concerning that he was vomiting before, stopped, and now started again. I'm also concerned that you describe him as pacing because that can be a sign of bloat. Boxers have deep chests and are very prone to bloat, which is fatal without treatment. Given that these symptoms have reappeared and he is prone to bloat, the best thing to do is take him into a vet right away. The vet can diagnose what is causing his symptoms and the best way to treat him. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Poor Bobby sounds like he is feeling unwell! I would avoid giving him tea as well, especially if it has milk in it. Dairy causes GI upset in dogs, and it may be making his vomiting worse. The only liquid he needs, even when sick, is water. He could be suffering from a severe GI illness, may have eaten something rotten, or could have a foreign body. It's a good idea that you have kept him off food since, and if he has been off food for 24 hours, feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.
