        Recommended exercise and nutrition

        Due to their small stature, Chihuahuas need to be gently exercised throughout the day, and should only be walked with a soft, wide collar or harness, to avoid putting too much pressure around their throat. Playing games and using treats and toys is a great way to allow your dog to burn off some energy and build a bond between you both.

        Your Chihuahua will not need a huge amount of food - however, it's important to consider their age, size and the time of day when preparing their meals. Always follow the guidance on the food packet.

          Half an hour of exercise a day

          If walking your Chihuahua, take them to a safe area without any obstacles that they might find difficult to cross, due to their short legs.

              Common health problems and illnesses

              Your Chihuahua will need all of the usual vaccinations and check-ups to help protect them against common ailments. There are some conditions which this breed is more prone to though, and you may want to familiarise yourself with the symptoms, so you know what to look out for.

                A common injury affecting this breed is a dislocated kneecap, also known as a luxating patella. This is a condition that they’ll have been born with, and signs to look out for include occasional skipping or hind-leg lameness. Simple surgery is usually the best way to treat this condition, but your vet can advise on the best course of action.

                  Chihuahuas are prone to a disorder called hydrocephalus, which is a build-up of fluid on the brain. It’s best to recognise the situation as early as possible. The liquid does two things; it debilitates the bones of the skull and misshapes them. The weight from this extra liquid pushes on the brain itself, bringing on neurological issues. Treatment relies on the seriousness of the condition and the disease progression.

                  Most cases are diagnosed when a dog is a puppy. The dog will have a large dome-shaped head. If you have any concerns, speak to your vet.

                    Tracheal collapse is a condition in which the trachea partially collapses or flattens out as your chihuahua is trying to breathe. This leads to irritation and results in gagging, coughing and wheezing symptoms. The trachea airway in your Chihuahua is a very sensitive area. It’s important that your dog get treated if they have this condition because it will get progressively worse without treatment. If you have any concerns, speak to your vet.

                      Dogs can get many of the same or similar oral diseases as are seen in people. However, whereas the most common dental disease in people is tooth decay or cavities, in dogs it is periodontal disease. Dogs with dental problems commonly show symptoms such as bad breath, excessive drooling, loss of appetite, and more.

                      As dog parents, we need to take good care of our dog’s teeth by regular brushing. We should also check our dog’s mouth regularly for early signs of dental problems. If you have any concerns, speak to your vet.

                        Chihuahuas can be born with a heart problem called a congenital heart murmur. Murmurs are caused by abnormal blood flow in the heart. This defect can be detected by a vet listening to a dog’s heart using a stethoscope, and it will often sound like a whooshing noise. Heart murmurs are very common and can simply disappear over time.

                          Grooming advice

                          Their short coat means Chihuahuas are relatively low maintenance. Regular brushing will keep their coat soft and tangle-free, and you will only need to bathe your dog once every month or two.

                          Your companion will either have a smooth or long coat. If smooth, their coat will be more fitted to the body and have a much shinier appearance, whereas if long, their coat could be flat or slightly curly and they'll have a long full tail. If you practice brushing your Chihuahua as a puppy, this will help in the long run and provide valuable bonding time for you.

                          Regular ear checks are needed to ensure there are no waxy build-ups and to prevent infection. Your pet will need their nails clipped regularly as they will grow quickly - if you can hear their nails tapping on the floor when they walk, they need cutting.

                          Just as with all other small breeds, your Chihuahua will be prone to poor dental hygiene, but brushing their teeth daily will keep any bacteria and plaque away.
