Some owners are surprised by the high price of feeding a growing Saint Bernard. Be prepared to feed your dog a healthy, high-quality diet that might be expensive, especially in the first year.
If your pup suffers from intestinal worms or malnutrition (and worms can cause malnutrition as well!), his growth might be stunted. You absolutely need to consult with a vet as soon as possible if you suspect your dog has one of these conditions.
The good news is that as soon as a worm infestation is cleared up with medications, your pup will continue growing and reach his normal adult height.
