How old were your dogs when you started walking them outside?

Hello po! Need ko lang po ng advice if ilang months po ang safe age for dogs to go outside? We all know na puppies have weaker immune systems that’s why they shouldn’t be let outside especially here sa PH. I’ve been very careful with this but 3 yrs ago, a relative took our 6 month old Belgian Malinois outside and he caught Parvo and died 😞 It was traumatic for me, and since then I’ve been extra vigilant with our dogs, especially puppies.

Currently, we have 2 new additions to the family. A male and female daschund, both 5 months old. I wanted to train them but its difficult because of their hyperactivity which caused a lot of damage to our furnitures 😅 I figured, walking them would reduce some of that energy but Im scared to let them outside 🥲

Btw, all our dogs are vaccinated and dewormed. That was the case too with our BM 3 years ago, but he still got sick.

Should I wait till our dogs become 1 yr old, before taking them outside?

Edit: Thank you po sa lahat ng advice, will take note of them po! 💕
