This process most often happens in a very specific order:
First the smaller front teeth come out, then the premolars, molars and finally the canine teeth will be the last to fall out.
For most puppies, the teeth fall out one by one and this may happen while your pup is eating or playing, so they are often swallowed and you may not notice that it has happened.
If at the age of 6 months, if your Chihuahua puppy
is still holding onto his puppy teeth, you should have a veterinarian perform a dental checkup.
In rare cases, an adult dog tooth will come in slanted and may affect the other teeth.
The loss of puppy teeth and the growth of adult teeth normally happen in this order:
• 4 Months old - the incisors begin to grow in
• 5 months old - the canine teeth begin to grow in
• 6 months old - the molars begin to grow in
By 8 months old, a Chihuahua puppy should have all teeth ascended and stop teething.
Do keep in mind that some are late bloomers and teething may last a bit longer.
