How long can I take him out for a walk in the morning and evening ? I am doing 10 mins right now but I feel that he still has so much energy after 10 mins of walk.
10 to 15 minutes per walk a couple of times a day sounds about right for a 3+ month old Havababy. Allow plenty of time for him to smell the grass, potty, and poop. For context, Ricky is 5 y.o. and we walk 50 minutes in the morning and 30 minutes in the evening, a total of about 4 miles every day, 7 days a week. He absolutely loves it! But this schedule is for a mature, athletic, fully developed Havanese. Puppies should be conditioned slowly until they are at least 1 y.o.
Regarding energy, I presume this is your first Havanese!
They can be VERY high energy, especially as puppies. Ricky has mellowed out a bit since puppyhood but even as an adult, after a 50 minute walk, he still wants me to play "zoomies" with him around the living room when we get home, at least for 15 minutes. He loves to get a toy and play "keep away" from me. He is bouncing off the furniture, growling, and racing as fast as he can in a confined space. And then he gets a drink of fresh filtered water, crashes, totally exhausted, and takes a morning nap.
Sounds like Senor Taco is a typical, happy, healthy Havanese male and YOU are going to have the time of your life with him!
You are doing a good job, keep asking questions.
