That is, are they physiologically ready to hold in their pee? Up to the age of 4 months, puppies find it hard to stop themselves peeing as their sphincter muscle isn't yet working properly. We know this period can seem endless, but remember that nothing lasts forever and with training (and lots of patience) your puppy will understand that pee goes outside!
Don't be upset, but you're the one who needs to be the most disciplined. If you know your dog just can't hold their pee in for more than a few hours...then you need to get them outside a few times a day.
Certain things encourage puppies to pee:
So, make sure you take your puppy out right afterwards.
When they do their business outside, really congratulate them to show they've "been good". It's all about positive reinforcement: promote learning and good behaviour by rewarding and encouraging rather than forcing them to act out of fear of punishment.
Is your dog well-trained, perhaps with professional help, but still peeing indoors? It's time to contact a vet to rule out any medical issues.
Incontinence can be caused by a range of health problems, with some easily treatable like cystitis, polyps and infections. Some neurological and hormonal issues can also cause incontinence. And older dogs are more sensitive to prostate problems, which can also lead to this issue.
If you notice your dog is suddenly peeing on your carpet, despite getting frequent walks, contact a vet who can give them the once over.
So, your dog's had ultrasound, scans and blood tests. And the results say they're in perfect health! (From a metabolic point of view!) So, they must be peeing in your living room or on your bed for behavioural reasons. If you're struggling to control your dog, they're barking a lot, or seem agitated, it might be worth contacting a dog behaviourist who can explore the reasons why. Have you moved house? Is there a new baby? Have you been separated, even unintentionally? Many factors can affect a dog's behaviour.
In any case, make sure you're a responsible owner and don't leave them alone for too long.
