Can I pray with dog hair on my clothes?

It depends on the school you follow. The Hanafi and Maliki schools consider a dog's fur pure, so a few hairs on your clothes do no harm. The Shafi'i and Hanbali schools treat the dog as najis, so they ask you to brush or wash the hair off first, especially if it is wet. Either way, your wudu is not broken.
Wudu and clothes are separate questions
Touching a dog, or finding its hair on your sleeve, does not break your wudu. The only question is whether your clothes count as clean for prayer. For the wudu side, see Does touching a dog break my wudu?
What the schools say
- Hanafi: the saliva is najis, but the dog's body and fur are not.
- Maliki: a living dog is pure, including its fur and saliva.
- Shafi'i and Hanbali: the dog is najis, including its fur, so loose hairs should be removed, and wet fur or saliva should be washed off.
The best-known hadith is about a dog licking a utensil. The Prophet ﷺ said the purification of a utensil licked by a dog lies in washing it seven times, using sand the first time (Sahih Muslim 279). That is about saliva, so the ruling on fur comes from how each school reads it. You can follow the school you have learned or the one your local mosque follows. If you are unsure, ask your imam which fits you. See Are dogs najis in Islam?
What to do before you pray
- Follow Hanafi or Maliki? You do not need to do anything about dry fur.
- Follow Shafi'i or Hanbali? Brush or lint-roll the hair off, or change your top. If the dog was wet, wash the spot it touched.
- Not sure? A quick lint roll before prayer satisfies everyone and takes a few seconds.
Floors, sofas and prayer mats
Dry paws on a dry carpet leave nothing to wash. The stricter view only asks you to clean a spot where wet paws, saliva or a wet dog touched. A prayer mat or a clean towel gives you a simple answer for any school. It also helps to keep the dog out of the prayer corner by closing a door while you pray. If a dog has licked you, see What should I do if a dog licks me?
Dogs are still creatures of Allah
None of this means you should be unkind to a dog. The Prophet ﷺ told of a man who gave water to a dog dying of thirst, and Allah approved of what he did and admitted him to Paradise (Sahih al-Bukhari 173). Hair on your clothes is a reason to keep a lint roller, not to push away a pet. See Can I keep my dog after becoming Muslim?
- Dog hair does not break wudu.
- Hanafi and Maliki: fur is pure. Shafi'i and Hanbali: remove it, and wash if wet.
- The seven-wash hadith (Sahih Muslim 279) is about saliva in a utensil.
- A lint roller and a prayer mat make it easy for every school.
