Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
How frustrating! However any time we have a dog who was doing great with house training suddenly not do great, I recommend give him the benefit of the doubt that he might have a medical issue that is causing this break in training. He might have a urinary tract infection, bladder stone, production of irritating crystals in the urine, etc.
That means it would be in his best interest to be seen by his veterinarian as soon as you can arrange this for an exam and urine check.
IF he has a check with his vet and everything looks to be normal, then at that time we can consign this to a behavioral issue and work to go back to the beginning with training (very frustrating).
Please let me know what questions you have.
That is certainly possible, but I have had several patients now that when straining to urinate are inspired to defecate from all the straining. For that reason alone I do recommend have him assessed for a urinary infection. The sooner the better because if we let this continue for too long, then it might become a behavioral problem (him defecating in the house).
Please keep me posted. I am always happy to answer followup questions. You can reply to this question at any time to submit a followup. My goal is to provide you with excellent service today. If there’s anything else I can do, let me know – it’s been a pleasure working with you and I hope to assist you again soon!
