First and second Dog :D

My first dog, a Rottweiler named Alika, has been with me for 4 years now. She is very outgoing and she always wants to play with me. Her favorite toy is a miniture Rottwiler doll which she rarely lets out of her sight. Two years ago though,  my friend Melissa's dog. a Dachshund named Samara, had three puppies and Melissa named them Nao, Minno and Yuyina.
Melissa decided give me a puppy and I chose Yuyina, the bi-colored one.
When I came back to my house with another dog, of course, Alika felt a bit jealous, but after a few days, she and Yuyina had become best friends.
Today, all of our lives are more enjoyable because, together,  Alika and Yuyina make our house a very happy place to live!

Good job! Thanks for sharing a picture of them! They are such beautiful dogs! As to the writing, my spellchecker changed "favorite" and "bi-colored" to the American spelling (without the British "u"). Both are acceptable, but just be aware that someone might say it is wrong or incorrect. Breeds of dogs are capitalized. Your sentence construction was a bit "wordy" and unorganized, so I tried to organize it more logically as above. Finally, Melissa can have a boyfriend, she can have the measles, she can even have pizza, but she cannot have puppies, right? Your sentence reads as if she gave birth to them, not Samara. As you proofread your work, in addition to looking for spelling or grammatical errors, make sure the sentence cannot be interpreted in another way as that one could. Keep writing and keep posting! It will get easier, I promise! I hope this helps you. J.

My first dog was a Rottweiler; Alika is her name.  She and I have been together for 4 years [or, alternatively, she has lived with me for four years].   She is very outgoing and she always wants to play with me.  Her favorite toy is a mini-Rottweiler doll that she  likes loves with all her life. that doll. Two years ago my friend Melissa had puppies in her house, including a Dachshund. Her dog's name is Samara, and she had three puppies--Nao, Minno and Yuyina.
Melissa decided to give me a puppy, and I chose a bi-colour Dachshund, Yuyina.
When  we  came to my house another my dog  Alika felt a few somewhat [or, a bit] jealous, but within a few days later Yuyina have been became her best friend.
Today our life is more funniest joyful because Alika and Yuyina make more happy our house happier.
