🐶 Dog Accidents in the House: Vet Guide 2025 to Causes & Solutions 🚫🏠

By Dr Duncan Houston, BVSc

Few things are more frustrating than coming home to an unexpected puddle or pile 💩. If your dog is having accidents in the house, don’t assume they’re misbehaving out of spite or defiance. Dogs don’t act out to “get back at you”—they're communicating that something’s wrong. 🐕💬

🩺 Medical Causes: Always Start Here

If your previously housetrained dog starts soiling indoors, the first step is always a veterinary check-up. Many medical issues can increase the urgency, frequency, or volume of elimination. These include:

• 🔬 Urinary tract infections (UTIs)
• 🧠 Neurological conditions
• 💉 Diabetes or Cushing’s disease
• 🥵 Pain or mobility issues that delay getting to the door
• 💩 Gastrointestinal upset or parasites

Veterinarians may recommend tests such as blood work, a urinalysis, or a fecal exam to pinpoint the issue. Treating the root condition often resolves the accidents—and a quick refresher in housetraining helps reinforce habits. 🧠📘

🧠 Behavioral Causes: It’s Not Always Medical

Once your dog gets a clean bill of health, consider behavioral reasons. Common causes of house soiling include:

• 🚫 Scolding during potty training (creates anxiety)
• 😨 Fear or dislike of the designated potty area
• 📍 Inadequate cleaning of prior accidents (scent remains)
• 🐾 Early learning history or insufficient housetraining
• 🚻 Marking due to hormonal or social triggers
• 💔 Separation anxiety or stress-induced urination

Remember: punishing accidents often backfires. Your dog may become anxious and avoid eliminating when you're around—only to sneak off and go in secret. 🕵️‍♂️

🔁 Housetraining Refresher: The Four Golden Rules

1. 🚪 Take your dog outside often, especially after eating, playing, or waking.
2. 🍖 Reward elimination outdoors immediately with praise or treats.
3. 🚧 Confine when unsupervised (crate, exercise pen, or gated room).
4. ❌ Never punish accidents—clean thoroughly and move on.

If your dog has regressed in housetraining or never fully learned, this structured approach can make a dramatic difference. ⏳🐶✨

🧼 Pro Tip: Cleaning Matters

Dogs have an incredible sense of smell. Even if an area “smells clean” to you, it may still smell like a toilet to them. Use an enzymatic cleaner to break down odor molecules. 🧴🧼

Use a blacklight to detect old urine spots—then clean thoroughly with a product designed for pet messes. Consider injecting enzyme cleaner into carpet padding if the area has been repeatedly soiled. 🕵️‍♀️🧽

🛑 What If It Keeps Happening?

If you’ve ruled out medical issues, restarted training, and your dog is still soiling indoors, don’t give up. More complex conditions like anxiety disorders, marking, or trauma-based behaviors may require tailored behavior modification and professional help. 🧠💡
