No appetite, trouble swallowing, chronic coughing, change in barking patterns, and just seeming restless and uncomfortable? These are all signs that your dog may have heartburn, or gastroesophageal reflux disease (GERD). GERD can make dogs very unhappy, but they have no way of telling their owners what’s going on.<\/span><\/p>\n

If you suspect your dog has GERD, you might want to know: What<\/span> antacid<\/span><\/a> can I give my dog? While most common over-the-counter heartburn medications are safe for dogs, it’s important to consult with a veterinarian to determine the best treatment plan based on their symptoms and medical history.<\/span><\/p>\n

Why your dog might need antacids<\/span><\/h2>\n

Antacids work by reducing the acidity of stomach contents. They can be helpful for dogs with conditions that cause heartburn or reflux. According to<\/span> Anna Panyutin, DVM<\/span><\/a>, a small-animal internal medicine specialist at South Carolina Veterinary Specialists and Emergency Care, there are two main conditions they can help treat.\u00a0<\/span><\/p>\n

    \n
  1. Gastroesophageal reflux disease (GERD): <\/b>The most common reason to use antacids in dogs is to treat<\/span> gastroesophageal reflux disease (GERD) or acid reflux. Antacids “help reduce irritation and inflammation of the esophagus and throat caused by the acid in refluxed stomach contents,” Dr. Panyutin explains.\u00a0<\/span><\/li>\n
  2. Gastric ulcers: <\/b>Though less common, antacids can also be used to treat stomach ulcers in dogs. “The use of antacids in dogs is supported when a stomach or upper small intestinal ulcer\/ulceration (or ulcerative esophagitis) is known or strongly suspected, to reduce further injury and promote healing of the ulcer,” Dr. Panyutin notes.\u00a0<\/span><\/li>\n<\/ol>\n

    Which antacids can I give my dog?\u00a0<\/span><\/h2>\n

    At appropriate doses for dogs, most human antacids are also safe for pups, according to Dr. Panyutin. However, the most effective treatment for acid reflux in dogs is proton pump inhibitors like Prilosec (omeprazole), she says. The following types of acid reducers could help your four-legged friend, with a vet\u2019s supervision.<\/span><\/p>\n

    Antacids<\/span><\/h3>\n

    Most of us are familiar with<\/span> Tums<\/span><\/a>, which are over-the-counter, chewable<\/span> antacids made of calcium carbonate<\/span><\/a>. Tums work by neutralizing stomach acid and primarily treat heartburn and indigestion.<\/span> Tums can be given to dogs<\/span><\/a>, but you should consult with your vet before doing so. Your vet can give you info on how many Tums are safe to give your dog and how often you can give them.<\/span><\/p>\n

    Proton pump inhibitors (PPIs)<\/span><\/h3>\n

    Omeprazole<\/span><\/a> is a proton pump inhibitor antacid sold under the brand name<\/span> Prilosec<\/span><\/a>. Dr. Panyutin says that it’s the preferred choice for use in dogs with reflux. “Only proton-pump inhibitor antacids, such as omeprazole or its sister drug esomeprazole, have been shown to be truly effective in dogs in veterinary studies and thus are the preferred choice,” she explains.<\/span><\/p>\n

    One important note is that omeprazole shouldn’t be given for extended periods. “When you block acid for a length of time, there can be a rebound acid production\/release that can have painful and deleterious side effects,” explains Laurie McCauley, DVM, veterinarian at<\/span> Optimum Pet Vitality<\/span><\/a>. She recommends limiting omeprazole treatment to six weeks.\u00a0<\/span><\/p>\n

    H2 blockers<\/span><\/h3>\n

    Pepcid<\/span><\/a> is the brand name for<\/span> famotidine<\/span><\/a>, an H2 blocker that decreases stomach acid production. It can be used to treat acid reflux and is sometimes used \u201c<\/span>off-label\u201d to treat ulcers in dogs<\/span><\/a>. Famotidine formulations include tablets and liquid suspensions. Sometimes it’s administered as an injection by your vet.<\/span><\/p>\n

    Antidiarrheals<\/span><\/h3>\n

    Kaopectate<\/span><\/a> is mostly used to<\/span> treat diarrhea, but it\u2019s also considered a gastrointestinal protectant<\/span><\/a> for minor reflux in dogs. It is available in liquid form and should only be given when recommended by a veterinarian, who can provide specific instructions for use in your dog. <\/span>In rare cases, it can cause constipation.<\/span><\/p>\n

    Important considerations before giving your dog antacids<\/span>\u00a0<\/b><\/h2>\n

    The most important thing to keep in mind before giving your dog antacids is that you shouldn’t initiate their use without first discussing them with a veterinarian. “The use of antacids is not benign, and while they may be necessary in appropriate disease contexts, their use should be limited only as long as truly necessary,” Dr. Panyutin emphasizes.<\/span><\/p>\n

    Dr. Panyutin also notes that all antacids have side effects, a phenomenon well documented in humans, especially with long-term use. “While there is a gap in research identifying the same breadth of antacids’ side effects in dogs, we do at least have some evidence that they can result in gastrointestinal dysbiosis, or an imbalance of the normal bacteria within the gut, which can result in GI upset, such as vomiting, diarrhea, and inappetence,” she says.<\/span><\/p>\n

    These side effects\u2014loss of appetite and gastrointestinal upset (vomiting, diarrhea)\u2014are among the most common Dr. Panyutin sees in her veterinary patients.\u00a0<\/span><\/p>\n

    When antacids aren’t enough<\/span>\u00a0<\/b><\/h2>\n

    You know that an antacid is working when your dog’s symptoms have decreased. If their symptoms are not improving or even worsening, it’s time to return to your veterinarian to discuss alternative options.<\/span><\/p>\n
