Our 9 month old Labrador had not been himself over the last few days. Over a week ago he had kennel cough and was prescribed loxicom (an anti inflammatory). He recovered well from the kennel cough and finished the loxicom after a week as directed. He then started to behave strangely. It was almost like anxiety symptoms and not his usual bouncy self. He started vomiting and not wanting to lie down. He went down hill very quickly with lethargy, dribbling and vomiting and we saw a vet Friday who thought he had developed a secondary infection from the kennel cough so prescribed pain killers and antibiotics. Bloods taken were normal. She sent us home. As directed i had to force these tablets in to him. I feel so guilty about this now knowing what followed. That night he struggled to lie down and vomited even after having an anti sickness injection at the vet. he would go and just stand in the garden staring straight ahead. The next morning he was worse so took him back to vet. Different one this time who saw he was very unwell by this stage. He had bloods again and an ultrasound. Vet though he had a foreign object in his tummy so they did an operation to remove it. This was not the case. They found a huge ulcerated stomach and digestive tract and massive internal bleeding. No perforation thank goodness. It is now watch and wait to see if he recovers. We are devastated. I checked the dosage of the anti inflammatory and all correct and given with food. The vet can’t say for certain if these caused the ulcerations. She also wondered if he had some how ingested a toxin but nothing we can think of. Has anyone had any similar experiences. He’s such a lovely, young dog and I can’t bare to think he won’t make it.
