Answer

### Step-by-Step Text Solution:

1. **Understanding Breeding Types**: First, we need to understand the different types of breeding classifications. Animals can be classified as continuous breeders, seasonal breeders, monoestrus, or polyestrus based on their reproductive cycles.

2. **Defining Seasonal Breeders**: Seasonal breeders are animals that mate only during specific times of the year. This means that their reproductive activities are restricted to certain seasons.

3. **Identifying Dog's Breeding Behavior**: Female dogs, also known as bitches, typically have a reproductive cycle that includes multiple estrous cycles throughout the year. However, they are not continuously in heat and do not breed at any time of the year.

4. **Understanding Estrous Cycle**: The estrous cycle in dogs is known to be approximately 6 to 12 months long, with most breeds having 1 to 3 cycles per year. During the estrous phase, female dogs are receptive to mating.

5. **Conclusion**: Given that dogs do not breed continuously throughout the year and have specific times when they are receptive, they can be classified as seasonal breeders.

6. **Final Answer**: Therefore, the correct answer to the question "Dog is a?" is **B. Seasonal Breeder**.
