Poor Brutus. He's such a cutie! It sounds like the cat food has upset his stomach. Feed him 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 he refuses to eat the bland diet, 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.

Hello, sorry to hear about Brutus. A decreased appetite and lethargy are non-specific sings that something is not well. This could be anything from an infection to a mass. This could also be temporary and resolve on its own within the next 2-3 days, however, the ideal next step is to have him evaluated by his veterinarian. They will likely require to obtain some bloodwork and x-rays or and abdominal ultrasound. In the interim, you may feed him a bland diet of plain white rice, skinless and boneless boiled chicken, and low fat cottage cheese. Hope this helps and best of luck.

While we were away, our dog ran out of food (Iams minichunks). His sitter picked up a small bag of grain-free food (forget the brand). When we returned we bought him a bag of Pedigree for adult dogs. Now he has been eating grass, vomiting, and his no
I'm sorry to hear that Django hasn't been feeling well! Sudden diet changes can cause acute episodes of gastroenteritis (inflammation in the GI tract), which can lead to vomiting, nausea, and diarrhea. You can try continuing to withhold food for the rest of the day today, then offer small frequent amounts of a bland diet starting tomorrow morning. Feed boiled white meat chicken and white rice (1 cup for every 10 pounds of body weight) for several days if his vomiting and nausea subside. After a few days, gradually mix his normal food in with the bland diet over another 5-7 day period. All of that said, if Django remains lethargic, refuses to drink any water, or experiences profuse vomiting, he should be examined by a vet because he may need fluids or other medications. I hope that he feels better soon!

My dog ate 15 thick slices of raw bacon yesterday and I took him to the vet. They induced vomiting but he only vomited 5 of the pieces up. Last night he ate dinner but he only pooped small pebbles last night after dinner and has not pooped since th
Fast him until tonight. Offer small amounts of water or unflavored PediaLyte throughout the day. Consider feeding him a bland diet in small, frequent amounts for the next few days then transition slowly to his regular diet afterwards. Monitor for vomiting, diarrhea, loss of appetite, lethargy or abdominal pain. These are symptoms that should be addressed by your veterinarian.

My 9 year old basset threw up 5 or 6 times. He's lethargic, possibly a little bloated. He hasn't thrown up in a little while. My partner - who's had him 7.5 years longer than me - says this happens and when he rushes to the vet it's nothing. Mayb
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.

I have a baby pug he's 6 months old he ate some cat food and I took the cat food away and he throw up and then I notice he was shaking and he looks dizzy what can I give him to help him feel ok please help
withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If he continues vomiting or is not eating, take him to the vet to get treatment.
