How Often Should You Feed Shih Tzus Puppies?

When you bring home a new puppy, it is important to understand how you can best support healthy growth through exercise and diet to help them reach adult size. The frequency at which you should feed your pet depends on various factors, mainly their age as stipulated below. 

  • Make it a point to provide the puppy with three meals daily during the first year after the completion of those three months.
  • Even though it will be advisable to provide your Shih Tzu canine with as many as two to three meals every day, some pooches like to be fed only a couple of times every day. Here, of course, we are talking about the main meals. While this still okay to do, we do suggest you refrain from feeding them only once a day. As humans we wouldn’t cope being fed once a day so you should not do the same to your furry friend.
  • It is a fact that a Shih Tzu is prone to suffer from hypoglycemia (low blood sugar) during their puppy stage, especially when they are less than three months old. Consequently, make sure to feed them often with fresh food items for preventing this condition.

Is Your Shih Tzu Healthy?

Shih Tzu’s are generally a healthy breed of dog but like human beings, they can also suffer from some ailments that can effect the Shih Tzu’s health.

If you’re concerned about your pups health, consider taking them to your local veterinarian.  

Common Health Problems of Pet Shih Tzus

Breathing problems: On some occasions, a Shih Tzu canine might find it somewhat difficult to breathe mainly because of the shape of their head as well as face and airways. At times, it will be a good idea to take the help of surgical procedures for widening the airways so that it becomes somewhat easy for the canine to breathe while having an adequate supply of oxygen.

Eye issues: These adorable creatures can also suffer from cataracts. This particular condition can prevent the pup from being able to see properly. If you think your pet is having issues seeing, make it a point to visit your vet for expert advice. 

Ear infections: At times, these friendly canines also struggle with ear infections, which can happen because of the excessive growth of bacteria or yeast. In that case, it is advisable to treat this condition with proper medication so that the canine will stop displaying symptoms related to ear infections, such as too much shaking of the head and so on.

Joint issues: A Shih Tzu may be prone to hip dysplasia over the course of their life. Hip dysplasia is a painful genetic health concern where the hip joints develop abnormally causing your furry friend, pain and discomfort. The only way to prevent this condition is by ensuring dogs that do exhibit the condition, are not bred from as this is a genetic health problem. Shih Tzus can also be prone to back problems due to their long back. The most common back condition in this breed is the intervertebral disk disease. This condition refers to the intervertebral disks which are there to cushion their spines. When it bulges or ruptures, it can cause nerve issues as well as severe pain.
