My dog Alfie, He is souch a sweet and affectionate boy.

He loves histo go for walks.

You can also say, "He loves to be taken for walks."

He’s a very charming boy.

One time he stole thea donut and ate it all.

He is out going and love hiss to go for walks and meet friends.

"Outgoing" is written as one word.

He followeds me every single day.

You could use "followed" if you were talking about something your dog did in the past. Since you are talking about something he still does (his current actions), this sentence should be in the present tense too.

It’s cute, though.

I love him to bits. He hates having a bath.

My dDog (Alfie)

Titles need capitals, brackets is a stylistic recommendation.

My dog’s name is Alfie, Hhe is souch a sweet and affectionate boy.

Such a - implies a lot (stylistic)
Commas don’t equal a capital

He loves his walk.s./He loves going on a walk.

Walks = plural, a habit/activity.

He’s a very charming boy.

“He’s a good dog.”
“He’s annoying.”
“He’s a strange person.”
Adjectives don’t need ‘a’, but extended descriptions do need an a.

One time he stole thsome donuts that I bought and ate it all.them.

He is out going and love his walks meeting new and meetold friends.

You’ve already said walk so I’ve corrected it.

He followed ms me around the house every single day.

Just some context and follows me - implies a continuing habit into the present, followed = past participle = the past

It’s cute tho.

I love him to bits.H Also, he hates having a baths.

These are two separate things so I’ve added ‘also’.

“He hates zoos.”
“He hates dogs.”
It needs to be a plural to imply all baths.
