Yes. Animals are terrified of vampires. Bella mentions on their honeymoon that she'd swim with the dolphins...but they'd disappear the moment Edward got into the water...as if he were a great white shark. Bella also mentions how animals won't go near her after she becomes a vampire. Even birds won't fly near a vampire. Jacob would show Renesmee the early morning birds flitting around...but the moment a Cullen appeared then the birds would vanish. This explains why the Cullens don't have any animal pets. Even humans have a natrural aversion or natural fear towards the Cullens (& other vampires) and avoid them at great length. Bella just didn't possess this natural aversion. This is why the Cullen kids were never popular or had any friends in school until Bella moved there. In Bella's senior year, Edward and Alice joined Bella's lunch table. The books explain how difficult this was for Bella's human friends. Even sweet natured Angela found it difficult to sit next to Alice wihout feeling creepy.
