Chihuahua versus Portuguese Water Dog: Overview
A very important difference between the Chihuahua and the Portuguese Water Dog is the size difference between the two dog breeds. The Chihuahua is a tiny-sized dog while the Portuguese Water Dog is a medium-sized dog.
Furthermore, the Chihuahua belongs to the Companion Dogs group. Companion Dogs were bred to be companions for humans. Their main goal in life is to be with people, and they will be very sad if left to themselves for long hours day after day.
On the other hand, the Portuguese Water Dog belongs to the Working Dogs group. Working Dogs were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks, guarding homes, and protecting their families. Breeds in the Working Group are known for their imposing stature, strength, intelligence, and fearless. Because of their size and strength, working dogs require a structured home life and firm, fair, consistent training by someone who can provide leadership without resorting to anger or physical force.

Most of the factors in the table for each dog breed are ranked on a scale of 1 to 5. “1” means “worst”, and “5” means “best”.
However, some factors such as “Price”, “Average Lifespan”, etc. cannot be on a scale of 1 to 5, so they are not on a scale of 1 to 5 in the comparison table.
Later in this article, we will further explain each factor as it applies to the Chihuahua and the Portuguese Water Dog

Next, we added the scores of the factors that can be added together for the Chihuahua in the table (that is, `Ease of Grooming` score + `General Health` score + `Calmness` score + …etc) and we compared it to the corresponding total score for the Portuguese Water Dog. We call these total scores the Better-Pet Scores, as we mentioned earlier. We called this score the Better-Pet score because the better dog breed will have a higher score. This is because the pet will the higher score will have minimal needs and be easier to have as a pet.
The Better-Pet score for the Chihuahua is 84 out of 125 while the Better-Pet score for the Portuguese Water Dog is 84 out of 125.
Despite the equal Better-Pet score of the Chihuahua and the Portuguese Water Dog, we still think that the Chihuahua is a better pet than the Portuguese Water Dog.
This is because Chihuahuas are much cuter but you cannot put a score on cuteness. If you could put a score on cuteness, then the Chihuahua will come out on top.
Also, we are biased in favor of the Chihuahua :-). We are for the Chihuahua. So get a Chihuahua!
