I have a 10 month old Frenchie who is just the sweetest ball of energy. I got him in September so this is his first summer. I have read everything about overheating and have now totally freaked myself out. He is just so energetic and has no off switch. We live in WI so it hasn't been too hot but he gets so excited when we're on walks and then starts panting. It sounds like he has some phlegm but he shows no other signs of distress, though did gag once but it didn't seem to effect him much. He asks to go out again as soon as we get home. We don't even go for that long and we never had this problem until this last month. He loves playing with other people and dogs. I just don't know how much is too much. I don't want to deprive him but I don't want to put him at risk either. Any advice on realistically raising a happy, healthy Frenchie and calming my anxiety would be much appreciated.
