Pls. come train my dogs. I have five, two of which are hounds. One is a coon hound/red tick mix and one is a beagle. I have a large fenced in kennel area but unlike your hounds, if I let them out or off lease I might see 'em in a day or two.
We have 1 1/4 acre fenced in the back yard. It took three layers of fencing to keep the Beagle in. The Greyhounds won't jump over but the Beagle used to go over, under, around and through. She's too old for those tricks anymore. She used to go through the fence like toothpaste coming out of the tube. Field fence, chicken wire and finally garden fence kept her in. She cost $15 from the shelter and $1,000 for fencing. None of them are allowed out of the yard off leash.
