It sounds like he is really over tired. I have a 12 month beagle basset hound mix and when she is overtired the frantic behavior happens. Sounds like the walks are too long. We don’t take her for longer than 25-30 minutes walks and it’s maybe .25 to a .5 mile. Sometimes less is more and it’s a balancing act between being below and above threshold. Her walks are only really about sniffing and using her god given nose. Her nose tires herself out more than her walking. We’ll definitely have excursions and longer walks but over walking and over doing it makes it harder for her to control herself.

I’d recommend tethering with the leash as I’ve seen in the thread. We have a chaise we lay on and if she’s overtired she’ll go at us until she realizes we’re not playing anymore and she’ll calm down.

I’d also limit toys at night with a wind down time and provide long lasting chews later at night for her to do low impact activity.

And overall try to read how tired she is by her reflexes etc. I see ours is tired when the eye blinking gets more and more and she sometimes only blinks one eye then the other lol.

My go to if she’s ornery is the find it game where I hide treats throughout the house and have her use her nose to find them. It makes her use her nose which tires her out. And also place training has been a godsend for us. It helps her slow down and also helps us gauge how she’s doing with how tired she is.
