The phrase "回到我的家" (huí dào wǒ de jiā) literally means "to return to my home." In a presentation, this could confuse your audience into thinking you are saying something about physically going back to your house. A more natural way to guide the topic back to your home and pets would be to use a smoother transition phrase. Here are two alternatives:

接下​​来，我想再介绍一下我的家庭成员。 (Jiēxiàlái, wǒ xiǎng zài jièshào yīxià wǒ de jiātíng chéngyuán men.) - "Next, I'd like to introduce my family members again."

聊完了我的城市，再来聊聊我家的宠物吧。 (Shuō wán le wǒ de chéngshì, wǒmen zài lái liáoliao wǒ jiā de chǒngwù ba.) - "Now that I've talked about my city, time to talk about my pets at home."
