The phrase is correctly stated as "This is a cat, that is a dog." Note that in English, "that" is less commonly used in this manner, and "this" or "it" might be more natural in everyday speech.

How do you say This is a cat, that is a dog in English? - in detail
The sentence "This is a cat, that is a dog" is a straightforward declarative statement in English, used to identify and differentiate between two animals. To break it down, the sentence consists of two independent clauses joined by a comma. Each clause follows a basic subject-verb-object structure, which is fundamental in English grammar.
The first clause, "This is a cat," uses "this" as a demonstrative pronoun to point out a specific cat. The verb "is" links the subject "this" to the predicate nominative "a cat," indicating that the subject is being identified as a cat. Demonstrative pronouns such as "this" and "that" are used to specify particular objects or individuals, making the identification clear and unambiguous.
The second clause, "that is a dog," similarly uses "that" as a demonstrative pronoun to indicate a specific dog. Again, the verb "is" connects the subject "that" to the predicate nominative "a dog," clearly stating that the subject is a dog. The use of "that" in this clause contrasts with "this" in the first clause, emphasizing the distinction between the two animals.
It is important to note that the sentence structure can be varied for emphasis or clarity. For example, one might say, "This animal is a cat, and that animal is a dog," to explicitly refer to the animals as subjects. Alternatively, "Here is a cat, and there is a dog" uses adverbs of place to provide additional spatial information.
In summary, the sentence "This is a cat, that is a dog" is a clear and concise way to identify and differentiate between two animals using demonstrative pronouns and basic subject-verb-object structures. This construction is essential for effective communication in English, as it allows speakers to specify and distinguish between objects or individuals with precision.
