Given the extensive length of the article that you’ve requested, that would not be capable of being carried out by the AI.

However, I’d be happy to give you a “sneak peek” on what the document could appear like in terms of structure and content, depending on some of the key issues that could be discussed in such a comprehensive context.

Various sections like:

1. Understanding the Importance of Dental Care in Small Dogs: In this part, the text would delve into the role of dental hygiene in the overall health of small dogs. This includes the prevention of gum disease, tooth decay, bad breath, and more severe conditions like periodontal disease which affects the dog’s organs.

2. Identifying the Signs of Dental Problems in Small Dogs: This section would arm readers with knowledge on what to look out for to identify dental issues promptly. Symptoms could include bleeding gums, bad breath, change in eating habits, yellow-brown crust on teeth, etc.

3. Practical Steps to Improve Your Dog’s Dental Health: This segment would feature actionable measures that dog owners can take to keep their canines’ teeth clean. Points here would range from regular teeth brushing, provision of teeth-cleaning toys, to feeding a dental diet.

4. The Relationship Between Breed and Dental Health: Here, the article would explain how some breeds, particularly small and toy breeds, are more susceptible to dental health issues. It would provide some best practices for these breeds to counteract this genetically influenced propensity.

5. Importance of Regular Professional Dental Cleaning: This would stress the necessity of professional dental cleaning for small dogs, the process involved, and how often it should be done.

6. Coping with a Dog that Resists Dental Care: Practical tips would be offered here on dealing with dogs that resist having their teeth brushed or examined.

7. The Role of Diet in Dental Health: The article would dive into how the right diet can affect your dog’s teeth. Tips to select the best food for your dog’s dental health would be enumerated.

There would be sub-sections to break down the bulleted points above further. The delineation would be presented in a way that highlights the necessity of each point.

SEO keywords like “dental care for small dogs”, “dog’s dental health”, “professional dog dental cleaning”, “improving dog’s teeth health”, “signs of dental problems in dogs”, “dog’s dental hygiene” among others would naturally be integrated into the content in a non-obtrusive way to enhance search engine visibility.

Each section would feature well-researched, detailed content, with reference to studies, veterinary insights, and case studies where necessary.

But including all of this within a 15000 words article, including details and research would exceed the AI’s maximum output.
