Check out our guide for key warning signs and next steps, and <strong>be sure to schedule a vet appointment as soon as possible<\/strong>.<\/p>\n<h2>What Are Stomach Ulcers in Dogs?<\/h2>\n<p>Stomach ulcers are the result of the normal, healthy tissue of a dog\u2019s stomach being eroded away, so the condition goes well beyond a <a href=\"https:\/\/www.petpalaceresort.com\/the-best-dog-treats-for-sensitive-stomachs\/\">rudimentary upset stomach<\/a>. Erosions can be minor (though troubling) in nature, or can be part of what is called a \u201c<strong>perforated ulcer<\/strong>\u201d that actually forms a hole in the stomach wall, creating the possibility of life-threatening sepsis.<\/p>\n<p>Stomachs have a protective barrier made up of layers of mucosa, which protects the stomach and other organs from stomach acid. Ulcers form as the mucosa weakens.<\/p>\n<h2>Symptoms of Stomach Ulcers in Dogs<\/h2>\n<p>Dogs can exhibit a number of symptoms with stomach ulcers, although some symptoms may overlap with other conditions. Review the following signs and consult with your veterinarian for a proper diagnosis:<\/p>\n<p><!-- ===== SYMPTOMS TABLE CHART ===== --><\/p>\n<div style=\"max-width: 980px; margin: 18px 0; font-family: 'Open Sans', sans-serif; font-size: 16px; line-height: 1.6; color: #32415d;\">\n<div style=\"overflow-x: auto; border: 1px solid #cfe6f3; border-radius: 10px;\">\n<table style=\"width: 100%; border-collapse: collapse; min-width: 720px;\" role=\"table\" cellspacing=\"0\" cellpadding=\"0\">\n<thead>\n<tr>\n<th style=\"text-align: left; padding: 12px 14px; background: #eaf5fb; font-weight: bold; border-bottom: 1px solid #cfe6f3; width: 28%;\" scope=\"col\">Symptom<\/th>\n<th style=\"text-align: left; padding: 12px 14px; background: #eaf5fb; font-weight: bold; border-bottom: 1px solid #cfe6f3;\" scope=\"col\">What to Look For<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 12px 14px; border-bottom: 1px solid #edf4f8; font-weight: 600; background: #ffffff;\">Vomiting<\/td>\n<td style=\"padding: 12px 14px; border-bottom: 1px solid #edf4f8; background: #ffffff;\"><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28276120\/\"><strong>~88% of dogs<\/strong> with ulcers<\/a> experience vomiting, often showing blood or digested blood (dark coffee grounds appearance)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px 14px; border-bottom: 1px solid #edf4f8; font-weight: 600; background: #f7fbfe;\">Melena<\/td>\n<td style=\"padding: 12px 14px; border-bottom: 1px solid #edf4f8; background: #f7fbfe;\">Black, tarry stools from digested blood.

They will want to know about the <strong>history of NSAID and steroid use<\/strong>, and they will likely perform blood work to check for anemia and protein loss.<\/p>\n<p>Ultrasounds are also commonly used to check for non-perforated ulcers, while X-rays can detect perforated ulcers. The most definitive test, however, is endoscopy, which uses a camera to detect ulcers, though exploratory surgery is also possible.<\/p>\n<h2>Treatment and Diet for Dog Stomach Ulcers<\/h2>\n<p>It\u2019s incredibly distressing when your pet is <a href=\"https:\/\/www.petpalaceresort.com\/why-is-my-dog-sneezing-so-much\/\">suffering from any kind of medical problem<\/a>, especially one as serious as a stomach ulcer can be. <strong>Thankfully, there are some treatment options<\/strong>:<\/p>\n<ul style=\"list-style: none; padding-left: 30px;\">\n<li style=\"padding-bottom: 15px;\">\u2705 <strong>Stopping any medications<\/strong> that could be creating the issue (as advised by your vet)<\/li>\n<li style=\"padding-bottom: 15px;\">\u2705 <strong>Using acid-blocking medications<\/strong> such as proton pump inhibitors, sucralfate, and misoprostol<\/li>\n<li style=\"padding-bottom: 15px;\">\u2705 <strong>Putting your dog on a bland diet<\/strong> to soothe their stomach, with <a href=\"https:\/\/www.petpalaceresort.com\/safe-and-unsafe-holiday-foods-to-feed-your-dog\/\">foods<\/a> like chicken, lean hamburger, white rice, low-fat yogurt, and cottage cheese \u2013 these last two items can help coat the stomach<\/li>\n<li style=\"padding-bottom: 15px;\">\u274c <strong>Avoiding <a href=\"https:\/\/www.petpalaceresort.com\/the-best-dog-treats-for-small-dogs\/\">hard treats<\/a><\/strong>, bones, and seasoned foods that could worsen the ulcer<\/li>\n<\/ul>\n<h2>Prognosis and Recovery<\/h2>\n<p>Once your vet has determined your dog\u2019s condition and the source of the ulcer, <strong>you have a good chance at recovery<\/strong>.

You need a veterinarian\u2019s guidance, diagnosis, and expertise. While a bland diet helps, prescription medications like proton pump inhibitors and sucralfate are necessary to stop acid production and protect the stomach lining so it can heal.<\/p>\n<h3>Does Helicobacter cause stomach ulcers in dogs like it does in humans?<\/h3>\n<p>Though Helicobacter bacteria lead to ulcers in humans, they <strong>do not appear to be a contributing factor for dogs\u2019 ulcers<\/strong>. The bacteria are found in nearly 100% of healthy dogs, and there is no compelling evidence that treating Helicobacter benefits dogs with gastrointestinal symptoms.<\/p>\n<h2>Need More Dog Health Tips?
